Quality & Stability Enhancements in ExtendSim 10

Enhancements & fixesQuality & Stability Enhancements in ExtendSim 10

We made a few tweaks in ExtendSim 10 that are important to maintain its quality and stability. Check here for the details.


From ExtendSim 10.0.6 to 10.0.7 • Released on November 12, 2020

Blocks • New and Improved Features

Batch (Item library)

bulletgoldCreated procedure Bprc_DynamicDataTable to enable dynamic linking to the batch quantities & attributes input dialog tables.

Executive (Item library)

bulletgoldAdded call to dlg_buildModelBlockConnsTable in BLOCKRECEIVE8.

bulletgoldAdded reference to new ASP include file and replaced calls to dlg* procedures with ASP* procedures in BLOCKRECEIVE8.

Resource Manager (Item library)

bulletgoldAdded new dialog button ExportResourceClasses_BTN in Resources table to manually trigger the creation of the [Resource Classes] table using current content in [Pools], [Resources], and [Groups] tables.

bulletgoldAdded call to RMdlg_enableDisableButton to manage a new button for exporting resource class definitions.

bulletgoldAdded new checkbox ExportResultsToSeparateTbls_chk to the Results tab to support new functionality for breaking out resource results in the [Resources] table to a separate table.

bulletgoldAdded a new dynamic array for use in the validation of resource requirement expressions table content.

bulletgoldAdded new variables and logic to better manage dialog refreshing.

bulletgoldAdded new data structures to more completely capture information for resource change groups.

Resource Pool (Item library)

bulletgoldMoved locally defined constants related to Resource Pool queues and allocation policies into the RP constants v10.h include file.

Throw Item (Item library)

bulletgoldNew implementation: Added an option to set an attribute with my Throw block number.

Merge & Diverge (Rate library)

bulletgoldAdded a warning to prevent the use of sensor blocks or sensing mode in Merge & Diverge blocks.

Component, Distribution Builder, End Node, Event Builder, and Start Node (Rate library)

bulletgoldAdded block Help.

HistogramHistogram (Chart library)

bulletgoldIncreased the maximum number of bins and maximum number of bars.

Line Chart and Scatter Chart (Chart library)

bulletgoldAdded the ability to filter data on schedule in continuous models.

Chart & Report libraries

bulletgoldCleaned up categories for all Chart and Report library blocks and hid them in the Library menu. Hidden Categories with respective Subcategories in the Chart and Report libraries are:

Chart > Bar Charts >
   • Bar Chart
   • Histogram

Chart > Line Charts >
   • DB Line Chart
   • Line Chart
   • Scatter Chart

Report > Information >
   • Item Log Manager
   • Reports Manager

Report > Statistics >
   • Cost Stats
   • DB Statistics
   • Statistics

Template library

bulletgoldEnhanced all hierarchical blocks in the Templates library with updated documentation.

bulletgoldqueue conditionsAdded new hierarchical block to the Templates library… Queue - Empty Based on Conditions that shows how to empty a Queue based on one of two conditions:

• When the Queue block is full.

• When an item has spent a maximum number of units of time in the Queue.

If either of these conditions are present, all items in the Queue will be forced to leave



Block • Fixes

Activity (Item library)

bulletgoldFixed the issue where  the current contents table was getting initialized when it shouldn't have been.

bulletgoldFixed user ability to store preempted remaining delay on the same attribute as the block's main processing delay attribute IF the user has left PEUseDelayAttribchk unchecked.

Create (Item library)

bulletgoldIf startIn is connected and if there's only one row in the schedule, non-zero create time should be allowed if PrgStartInBehaviorpop == FOLLOW_SCHEDULE.

bulletgoldIf prgStartInBehaviorpop = ONEITEMTHEN_WAIT, then the next item generated is a future event not a current event.

Executive (Item library)

bulletgoldRemoved old code which checked for the existence of too many Executive blocks in the model. It's been commented out because it is no longer necessary as ExtendSim now blocks users from adding a second Executive to the model.

History (Item library)

bulletgoldFixed the bug that would occur when siBlockWasScriptCreated was set, the variable would need to be copied in the DialogItem ScriptCreated. The value in the dialog item is used by the Mouse Click include.

bulletgoldIf the History block starts recycling the rows in ItemHistorydtbl, then ExtendSim will start recycling the records that have been written to in ILMMapInfo[].

Information (Item library)

bulletgoldCorrected the issue where the Icon was not animating at the beginning of the simulation.

bulletgoldAdjusted block position because there's a new Sensor connector on the top of the block's icon.

Queue (Item library)

bulletgoldCurrent contents table is no longer getting initialized when it shouldn't.

bulletgoldChanged the name of to CalcCosts to q_CalcCosts in order to accommodate generic costing logic.

Queue Matching (Item library)

bulletgoldCorrected some code in on updateStatistics that failed to check whether or not the block was/was not in Batch mode.

bulletgoldIf a departures list does not exist, don't try to calc ave length.

bulletgoldFixed the "dump group" input as ConnectorToolTipSet was indicating the wrong value.

Queue, Equation and Resource Item (Item library)

bulletgoldCorrected the current contents table from getting initialized when it shouldn't.

Read(I) and Write(I) (Item library)

bulletgoldIf a table is selected, blank out the rest of the coordinates because the new table likely wont have the same schema for field and record settings.

Resource Manager (Item library)

bulletgoldAdded a new dynamic array for use in the validation of resource requirement expressions table content.

bulletgoldAdded new variables and logic to better manage dialog refreshing.

bulletgoldAdded a new variable rMcostPerUsereleasedResources to enable accumulation cost per unit time in for released resources. This is used in calculating resource-based item costs.

bulletgoldAdded the explicit setting FCattribPop in FCInputVariableType_POP.

bulletgoldUpdated the RMprc_changeResourceProperty procedure to allow for resource shifts to be set to NULL/BLANK.

Resource Pool (Item library)

bulletgoldCorrected argument value being passed to update pending capacity value in RPfcn_calcNumberResourcesChanged.

Resource Pool Release (Item library)

bulletgoldAdded costing logic to AR_releaseResources to properly account for time-based resource costs.

Select Item Out (Item library)

bulletgoldWhen the label or attribute to animate is too long, it gets truncated. Stretch the animation object to fit the name.

Transport (Item library)

bulletgoldFixed that some models were getting corrupted and leaving animation objects on the worksheet which needed to be removed.

Write(I) (Item library)

bulletgoldAdded Item Quantity to the list of options for writing item information to the database.

Data Import Export (Value library)

bulletgoldNew code was added to handle fact that OLEObjectIsRegistered() was returning a false positive sometimes.

bulletgoldAdded conditional logic that depends on which type of ADO database is selected in the ADOWhichFilepop message handler. This fixed a problem when a selected ADO database is mySql.

Random Number (Value library)

bulletgoldFor the empirical table, the table was sorted at the beginning of the simulation. If the first column is string attributes, the indexes need to be sorted also.

bulletgoldIf there's a problem in setting a parameter, then abortallsims is needed. Not a simple abort; otherwise it would click in a loop as many times as the number of RunSimulation.

Read and Write (Value library)

bulletgoldThe function XL_OpenFile() is needed to return the workbook path selected by the user.

Convey Flow (Rate library)

bulletgoldIn an if/else statement, an else was missing making the else statement always applied.

bulletgoldFixed the quantity checking.

bulletgoldThere was no checking of the quantity in layers compared to the quantity in the Convey Flow block. The code was written but never executed. We now have quantity checking for attribute layers.

bulletgoldMade sure that the change to the status of the layer from intermediate to exit and also updated the last time update.

bulletgoldIn the case where an intermediate layer was transformed into an entering layer, the last time updated layer needed to be adjusted to currenttime, otherwise the quantity in the layer would be wrong.

bulletgoldAdjusted quantities when precision checking between quantity in block and cumul layer quantities did not add up. Added a warning message if the differences are too big.

bulletgoldThe variable siNoProductAtTheEndOfTheBlock needed to be updated as often as possible, changing the location on where it is updated as it was missing some update which caused the simulation to stop.

bulletgoldFixed the double call to on OpenExec_btn, so there is just one call.

bulletgoldThe first calculation of the content in the block (density and layers) was not updating properly at the beginning of a run. Needed a flag to allow the first calculation.

bulletgoldChecking precision was not enough to prompt the calculation of the amount of product in the tank creating a conflict proper updating of the data in the block (timing problem because rates may not have been updated yet) causing the layer amounts to be wrong.

bulletgoldA second element might be needed if the inflow rate was more than 0 as there might have been a new portion starting to fill up in a now empty Convey Flow block.

bulletgoldIn the case of a change of speed, the outflow rate was not always updating properly. It needed to consider the max output rate with new speed.

bulletgoldWhen checking on contents, if portion content is 0 the other content tolerance could be 1E-5.

bulletgoldWhen calculating portion after change of inflow rate, but at same time of the last change of Rate, if the Convey Flow is full, the model might lose the last portion containing the current inflow density at location 0. This caused some major problems not to having this information available for future calculations.

bulletgoldReviewed sensor logic where the sensor was not being set properly when at the limits.

  History(R) (Rate library)

bulletgoldFixed a bug that when siBlockWasScriptCreated is set, the variable needed to be copied in the DialogItem ScriptCreatedR. The value in the dialog item is used by the Mouse Click include.

Interchange (Rate library)

bulletgoldUsing the same mechanism that is in the Convey Flow block in the Interchange and Tank blocks. Try to avoid sending an update of attributes if the model knows there will be a recalculation of the effective rates. It is always preferable to update Effective Rates before the Attribute values.

bulletgoldWhen circumstances have changed while propagating new rates, an extra LP may have to be solved. (In this case, conditions have changed and no more exit layer is available.)

 Tank (Rate library)

bulletgoldNeed to check that the simulation is running to call a function when ReleaseOnAttriVal+prm is changed otherwise get an error message.

bulletgoldWhen initializing attribute layers, if cINITCONTENTSWITHOUTATTVALUES and an outflow connection is made, avoid allowing 2 empty entering layers.

bulletgoldUsing the same mechanism that is in the Convey Flow block in the Interchange and Tank blocks. Try to avoid sending an update of attributes if the model knows there will be a recalculation of the effective rates. It is always preferable to update Effective Rates before the Attribute values.

bulletgoldWhen circumstances have changed while propagating new rates, an extra LP may have to be solved. (In this case, conditions have changed and no more exit layer is available.)

Valve (Rate library)

bulletgoldIf change option on Executive block, assume the Advanced status option needs to be updated accordingly and not just enabled/disabled.

bulletgoldIf siStartingGoal + diValuesInIsConnected[cVALUESINGOAL] + !FirstGoalFixedchk, check the goal connector. Otherwise there may be differences from one run to another when doing successive runs.

bulletgoldThe reception of a new constraining rate no longer has anything to do with the connection to a goal, if the value changed with Link.

 Component (Reliability library)

bulletgoldNode Interrupt options now only show if the node has more than one event cycle.

bulletgoldThe name stored in the ID - Component Name field in the Component Set table needed to be altered.

bulletgoldIn models with many fail modes, calling RBDDBNEventsReg_GetEvents() in OpenModel2 slows the model as it does a sort on the event cycle names.

 Component & Start Node (Reliability library)

bulletgoldFixed SDEventsTblttbl and SDIntsTblfrm row indexes now start at 1.

 Distribution Builder (Reliability library)

bulletgoldTime units in distributions table are now getting updated properly in PreCheckData.

bulletgoldWhen opening the Distribution Builder dialog, by default it show the contents of the first record.

bulletgoldAfter committing, be open to more Link Alert messages.

bulletgoldWhen the number of records in the commit table becomes large, closing the commit table prior to committing speeds things up a lot.

 End Node (Reliability library)

bulletgoldSet EndNodeNameShowAboveIconchk = TRUE by default.

 Event Builder (Reliability library)

bulletgoldFound a problem with the ability of the Start Node and Component blocks to effectively open the Event Builder block remotely to the correct event cycle when the user clicks on one of the Edit Class buttons in the Event Cycles table.

bulletgoldAfter committing, be open to more Link Alert messages.

bulletgoldIn models with many fail modes, calling RBDDBNEventsReg_GetEvents() in OpenModel2 slows the model as it does a sort on the event cycle names.

bulletgoldWhen the number of records in the commit table becomes large, closing the commit table prior to committing speeds things up a lot.

 Start Node (Reliability library)

bulletgoldNo longer reporting the node name in the event log in the wrong format.

bulletgoldFor now, hide SDIntsTbl dialog items.

bulletgoldIf NoValue at allowRepair input, don't treat it as an error condition. There may be times when the input connector is actually a no value. Instead treat a no value as permission to repair. If the user wants to actively stop the repair, they will have to set the connector to FALSE.

bulletgoldOnly show Node Interrupt options if the node has more than one event cycle

bulletgoldChanged the name of Event Status table to Event Cycle Instances.

bulletgoldIn models with many fail modes, calling RBDDBNEventsReg_GetEvents() in OpenModel2 slows the model as it does a sort on the event cycle names.

bulletgoldThere were problems with the values at the valuesIn input connector getting updated properly at the beginning of the run.

 Buttons (Utilities library)

bulletgoldFixed an issue with copy/pasting equation code from one editor window to another editor window.

bulletgoldUpdated RMfcn_isResourceQEblocker to include "reassigned" resources as blockers.

bulletgoldCreated new function RMfcn_getRREexpressionGroupRec used for auto-generating resources.

bulletgoldAdded new argument to RMfcn_createNewFilteringCondition to allow for the specification and lookup of the filtering condition name.

bulletgoldAdded new logic to reduce overhead from string searches in RMfcn_executeResourceChange.

bulletgoldAdded crecordIndexChangePropertyName to support enhancement to dynamic resource change functions.

bulletgoldAdded a new call in RMmsg_onTabSwitch to RMdlg_enableDisableButton to manage a new button for exporting the [Resource Classes] table.

bulletgoldSet the new checkbox ExportResultsToSeparateTbls_chk to True in the CREATEBLOCK message handler.

bulletgoldChanged a parameter in the call to RMfcn_addResources to force auto-generated resource names to be distinct in the RMprc_addResourceClasses procedure.

bulletgoldNew logic added to reduce string-based searches in RMprcexecuteResourceChanges and RMprcchangeResourceProperty.

bulletgoldEliminated call to RMprcrequestRRdependenciesUpdate in RMprcexecuteResourceChanges and moved it to procedure RMprc_changeResourceProperty to update only the immediately affected resources to to reduce unnecessary overhead when making dynamic resource changes.

CHART_CONN_VariableInputConn v10.modl (Chart library)

bulletgoldAdded the ability to filter data on schedule in continuous models.

bulletgoldCorrected a mistake in naming of a function - should be CONA_OnConArrayChangedComplete instead of CONA_OnConArrayChangedCompleted.

CHART_DATA_Management v10.modl & CHART_DATA_Management v10.h (Chart library)

bulletgoldAdded the ability to filter data on schedule in continuous models.

bulletgoldChanged behavior: When Last point selected, it is now filtering out the new data when Y is not changing, but time is changing. It applies no duplicate after Last point filtering. It makes sense because otherwise cases with a lot more points than necessary might slow down simulation.

bulletgoldImprovement: The Histogram has now the option in multi-run Only end values like the Scatter.

CHART_DB_ValuesFromDB v10.modl (Chart library)

bulletgoldIncreased the maximum number of bins. Also the number of bins can be equal or lower, not strictly lower than max.

CHART_HIST_BIN_DataOptions v10.modl (Chart library)

bulletgoldAdded more details to error messages about the setting of the bins in the Histogram.

bulletgoldThe minimum axis should be the one set in the block if it is not supposed to be calculated.

bulletgoldLifted the restriction that bins had to be constructed at least once within the first run. It turns out that's too restrictive of a condition when gathering data across multiple runs.

bulletgoldBins only being constructed during the first run is too restrictive. This condition has been lifted.

CHART_HIST_CONN_DataOptions v10.modl (Chart library)

bulletgoldImprovement: The Histogram has now the option in multi-run Only end values like the Scatter.

bulletgoldIf draw Histogram is not during a simulation (with button) scaling should happen if scaling is only at end of simulation.

bulletgoldAdded a #Define COLUMN_TAGS_CONSTANTS_INCLUDE to identify the presence of the declared include in the block.

CONA_Manage_ConnectorArray v10.modl, CONA_Manage_ConnectorArray v10.mox, & CONA_Manage_ConnectorArray v10.h

bulletgoldAdded a constructor for the variable connector declared per position with each position linked to a different parameter.

bulletgoldAdded a constructor to reset data within includes before calling any other constructor.

bulletgoldAdded the use of new include: Miscellaneous general tools

Constants v10.h

bulletgoldGetDialogItemInfo with which==11 returns the position of the tab the dialog item is in (starts at 0).

bulletgoldAdded new costing constants.

DBDI DB selection from DI v10.h & DBDI DB selection from DI v10.h.modl

bulletgoldTo avoid having to declare the necessary includes in the main, do it conditionally within the include.

bulletgoldAdded a separate function to clear info before constructors. It is useful when constructors can be called from multiple includes.

bulletgoldImproved code: New DBDI_onLinkContentWithIndexes allows the use of parameters as inputs.

Dialog utilities v10.h

bulletgoldAdded a variable value field to the table created by dlg_buildModelDialogVarsTable.



Includes • Fixes

Diverge Merge v10.h (Rate library)

bulletgoldAdded a warning to prevent the use of Sensor blocks or sensing mode in Merge & Diverge blocks. Otherwise, it is slow, adds a lot of complexity, and is inaccurate most of the time.

Flow.h (Rate library)

bulletgoldIn some cases, individual blocks could be set to update at each step even if the global option in the Executive is set "as necessary". Checking is now more thorough.

bulletgoldAccording to the Executive global rule, the value of UpdateEachStep_chk needs to be changed in blocks.

Tank and Attribute v10.h (Rate library)

bulletgoldIn case the exiting layer does not exist (cOUTFLOW_FROM_ATT_VAL), it is possible that a new entering layer can make the exiting layer possible to select as the exit authorization needed to be updated.

bulletgoldWith the option cOUTFLOW_FROM_ATT_VAL, the search for the right exiting layer now works properly as it was using the wrong static variable to point to the Flow Attribute interrupting the simulation.

bulletgoldWhen initializing Attribute Layers, if cINIT_CONTENTS_WITHOUT_ATT_VALUES and an outflow connection is made, avoid ending up with 2 empty entering layers.

bulletgoldWhen a new layer becomes the entering layer, it is possible that this layer was neither cLAYER_S_INTERMEDIATE nor cLAYER_S_EXITING but is already set to entering. The if condition needed to be tightened to take this case into consideration.

bulletgoldIf a previous entering layer is empty, do not remove the layer when updating the quantity in the layer, do it right after the calculation.

bulletgoldWhen a candidate for the Exit layer is found, the first liLowerIDElement found was not set properly. This caused the Exit element to also not be set properly. This has now been fixed.

bulletgoldWhen a new value is received for the Attribute Value to exit the Tank block, when layers are updated, do not remove the empty layers.

Tank functions v10.h (Rate library)

bulletgoldAnimation bug fix: If animate level and capacity is infinite, the animation was wrong. It has now been hidden anyway because there wass no way to show a level if capacity is infinite (level is a percentage of capacity).

bulletgoldA message could attempt to send a value connector during InitSim causing the simulation to abort. Test to be sure you're in Initsim before sending the message.

bulletgoldWhen initializing Attribute Layers, if cINIT_CONTENTS_WITHOUT_ATT_VALUES and an outflow connection is made, avoid ending up with 2 empty entering layers.

bulletgoldUse the same mechanism as in the Convey Flow, Interchange, and Tank blocks. Try to avoid sending an update of attributes if you know there will be a recalculation of the Effective Rates. It is always preferable to update Effective Rates before the Attribute values.

DBN End Node v10.h, DBN Node v10.h, DBN Start Node v10.h, DBN v10.h, DBN v10.h, Dist v10.h, Distribution Builder.cm, & RBD Procs v10.h (Reliability library)

RBD DB Component & RBD DB Start Node v10.h (Reliability library)

bulletgoldThe name stored in the ID - Component Name field in the Component Set table needed to be altered.

RBD DB ECI v10.h (Reliability library)

bulletgoldCorrected the problems with the values at the valuesIn input connector getting updated properly at the beginning of the run.

RBD DB Start Node v10.h (Reliability library)

bulletgoldCorrected formatting for SDEventsTblNodeBlockName_txt.

bulletgoldRedesigned the Event Status table. It is now called Event Cycle Instances and has different fields and p-c relationships.

bulletgoldAdded an availability field to RBDDBRsltsEventSumTbltxt.

bulletgoldIf running, only package data at the end of the last run.

RBD DBN Indexes Get, RBD DBN Procs v10.h, RBD DBN Start Node, & RBD Procs v10.h (Reliability library)

bulletgoldWhen the number of records in the commit table becomes large, closing the commit table prior to committing speeds things up a lot.

RBD DBN Procs v10.h (Reliability library)

bulletgoldRBDDBNEvtReg_EventsList[] was getting sorted by blockNum instead of compID. This has now been corrected.

RBD DBN Start Node v10.h (Reliability library)

bulletgoldA row must be selected before attempting to set block icon view in the subsequent call to SDEventsTblBlockNum_Get(topRow).

RBD Procs v10.h (Reliability library)

bulletgoldSD_EventsTbl_NodeBlockName_txt was getting assigned a name to it that contained spaces which was causing an incorrect evaluation of it.

bulletgoldColumn headings in SD_EventsTbl_ttbl are now conditional.

bulletgoldConditional popup heading when adding a new event cycle instance for the Node-DE Interrupt.

bulletgoldAdded block Help.

bulletgoldDon't ever set evtReg to "N/A" because it has no meaning during the simulation run. Rather set to "ignore" and conditionally build the events table to show "N/A" when there's only one ECI.

bulletgoldSDEventsTblttbl and SDIntsTblfrm row indexes should start at 1.

bulletgoldFor now, hide SDIntsTbl dialog items.

bulletgoldSDEventsTblNodeBlockName_txt was getting assigned a name to it that contained spaces which was causing an incorrect evaluation of it. This has now been corrected.

bulletgoldOnly show Node Interrupt options if the node has more than one event cycle.

bulletgoldA row must be selected before attempting to set block icon view in the subsequent call to SDEventsTblBlockNum_Get(topRow).

bulletgoldCreated a new procedure RMdBprc_updateFieldProperties to update field properties in Pools and Resources tables.

RM dialog v10.h (Advanced Resource Management)

bulletgoldAdded the new procedure RMdlg_initializeFCpopups() to standardize the initialization of filtering condition popups.

bulletgoldAdded error checking for filtering condition popup variables that forces initialization if popup values are out-of-range.

bulletgoldAdded a call to RMdlg_populatePropertiesSourcesPopup in RMdlg_populateListOptionsPopup.

bulletgoldAdded a call in RMdlg_refreshDialogVariables(string tabName) to setDialogVariable to force the initialization of the ResourceGroup_POP popup.

bulletgoldCreated a new initialization procedure RMdlg_initializeMaxTextWidth to initialize maxTextWidth array. Added a call to this procedure before making calls to Dlg_setTableDisplayDimensions.

bulletgoldAdded a new procedure RMdlg_initDialogRefreshVars to initialize refresh management data structures.

bulletgoldAdded a call to RMdlg_hideUnusedDialogVariables() in the procedure RMdlg_setDialogVarsVisibilityInTab.

RM functions v10.h (Advanced Resource Management)

bulletgoldModified RMfcn_checkResourceReassignment to get the resource order ID from the resource's current value in the [Resources] table in.

bulletgoldAdded logic to accumulate cost per unit time in the new variable rM_costPerUse_releasedResources for released resources.

bulletgoldAdded a condition in the function RMfcn_getNumFCsInGroup to check to ensure the requirement expression property is equal to the quantity property.

bulletgoldAdded logic in RMfcn_executeQuantityExpression for testing results of quantity expression to depend on whether a procedure was executed from dialog.

bulletgoldAdded logic in RMfcn_executeQuantityExpression to prevent allocating less than minimum allocation quantity specified for the resource.

bulletgoldFixed the uninitialized variable problem in RMfcn_createNewFilteringCondition.

bulletgoldAdded explicit setting of count-based Resource Pool fields in RMfcn_addResourcePool.

RM message handlers v10.h (Advanced Resource Management)

bulletgoldCleared the reference to child resource order when releasing a resource order in RMprc_releaseResourceOrder(integer resourceOrderRecord).

bulletgoldAdded loop terminating condition when searching for matching property values in RMprc_setupResReqExpressionData(real i_arguments_ptr, real r_arguments_ptr, real s_arguments_ptr).

bulletgoldAdded code to set the rank value of a resource requirement in the RMprc_autogenResourceReqs procedure.

bulletgoldInitialized the static variable rM_costPerUse_releasedResources in RMprc_ReleaseResources procedure.

bulletgoldFixed error message outputs in RPprc_validateTotalResourcesCount.

bulletgoldFixed accounting for pending capacity changes including converting pendingCapacityChange from integer to real.

bulletgoldUpdated the user error message in RPprc_updateStaticVariableValue.

CHARTBARCONN_DataOptions v10.modl (Chart library)

bulletgoldUpdated the width of the columns after a possible change of name for categories or series.

CHARTBARCHARTCreateAndAddNewPoint v10.modl (Chart library)

bulletgoldWhen creating the Histogram, the default bins were not set in a proper order: Bin# 0, 3, 4, 1, 2 instead of Bin# 0, 1, 2, 3, 4.

CHARTBARCHARTCreateAndAddNewPoint v10.modl & CHARTBARCHARTCreateAndAddNewPoint v10.h (Chart library)

bulletgoldWhen increasing the maximum for categories in the Histogram, the existing blocks would not have their max changed because it is set in createblock. Made a change in oldfileUpdate updating existing Histograms.

CHARTDATAManagement v10.modl & CHARTDATAManagement v10.h (Chart library)

bulletgoldFixed problem with the cCHARTDATAFILTERNODUPLICATE filter, it did not properly filter data for Scatter and Line charts for filter Y when identical to X.

CHARTHISTBIN_DataOptions v10.modl (Chart library)

bulletgoldFixed problem where the maximum is fixed and not being taken into account when creating bins, but the maximum value received was taken into consideration instead.

bulletgoldIncreased the maximum number of bins. Also the number of bins can be equal or lower, not strictly lower than the maximum.

CHARTHISTCONN_DataOptions v10.modl (Chart library)

bulletgoldIf setup recording during the simulation, the resize of the table might not be enough causing an error message. This has been corrected.

bulletgoldIn multi-run, the Histogram from one run to another would not reset the bar values properly because of a confusion between passing an argument series instead of bar. This has been fixed.

bulletgoldThe wrong column was being used to set negative reset values in cCHART_HIST_SERIES_I_ONLY_ONE_RUN_NUM and not cCHART_HIST_SERIES_I_SCHEDULE_ROW.

bulletgoldThe option cCHART_HIST_UPDATE_AT_END_SIM now works properly.

CONAManageConnectorArray v10.modl, CONAManageConnectorArray v10.mox, CONAManageConnectorArray v10.modl, & CONAManageConnectorArray v10.h

bulletgoldIn CONA_TrueIfConnected, it was returning an error code of 0 instead of the -1 expected.

DBDI DB selection from DI v10.modl

bulletgoldIf the database table was not selected, the dialog text was not disabled. Now Record ID is disabled if no table has been selected or the selected table has no ID field.

bulletgoldIn function call DBDI_RemoveDBSelectionUpTo, the dialog values were not erased, only the internal data within the include. The dialog has to be blank also.

bulletgoldIn case the record selected had modified its ID name, the ID name was not always updating in the dialog. Needed to update the value if necessary and not skip validation.

bulletgoldIn the case where a database table or field is being selected and the index is the same, it needs to check that the name is still up to date before returning and changing nothing. There was an issue when name DB/Table/Field would change and not be valid anymore, but not being updated either.

bulletgoldTo avoid looping in LinkContent and LinkStructureNone initialize values for flag .

Equations v10.h

bulletgoldCall GetSimulateMsgs(TRUE) if model is continuous.

bulletgoldChanged the UserError wording for describing when the equation cannot find the specified include file.

bulletgoldEnhanced the search for prototypes in users' include files.

bulletgoldFixed a bug with tracking the right Link Alert input variable name.

lp_solve v10.h

bulletgoldChanged the error message as it needed to be shorter since it was getting truncated.

From ExtendSim 10.0.5 to 10.0.6 • Released on February 11, 2020

Blocks • New and Improved Features

Information (Item library)

bulletgoldAdded area counting.

Resource Pool Release (Item library)

bulletgoldAdded a popup menu and associated logic in passItem to allow users to specify block behavior when passing items have invalid release attribute values specified.

Diverge, Catch, Flow, ThrowFlow, Tank Merge, Interchange (Rate library)

bulletgoldProtected the code in the Rate library including moving some includes to a Not installed folder.

End Node (Reliability library)

bulletgoldAdded the down(CS) output value connector. It is needed for proper communication with the Valve block.

Start Node (Reliability library)

bulletgoldAdded a new table, Results_Tables_ttbl, that supports overlapping event handling for the Node Summary and Event Summary tables and enhances the Results tab user interface.

Added the down(CS) output value connector. It is needed for proper communication with the Valve block.

Histogram (Chart library)

bulletgoldHistogramThe Histogram block displays statistical information, using bars to show the frequency of data sets (series) in successive numerical intervals of equal size (bins).

Scatter Chart (Chart library)

bulletgoldUpdated the dialog for a multi-run trace by removing checkboxes, replacing them with options and a Per Trace For Run column (additional multi run option: all runs, only end values)



Block • Fixes

Create (Item library)

bulletgoldCorrected calls to prgSVT_OnPrg_dtbl().

Executive (Item library)

bulletgoldIf SA_Names_ttbl is out of bounds, it will ignore user clicks.

bulletgoldWhen there is a problem, it will break out of string attribute loop.

bulletgoldThere was a problem with the simulation order being different than 1 in a model where the simulation order is set to Custom. If it happens on openmodel, ExtendSim will change the simulation order to 1. If it happens when simulation starts, ExtendSim will interrupt the run with an error message.

Exit (Item library)

bulletgoldNow allows the pulling of upstream items for the first (currentTime=0) scheduled event by setting diConToPullItemsFrom[i] = True.

Resource Manager (Item library)

bulletgoldForces the total allocation time to be equivalent to the total busy time.

bulletgoldFor now, in RMprc_updatePoolStatusTime, set the total quantity allocation time equal to total busy time.

Resource Pool Release (Item library)

bulletgoldChanged the order in which SetupDialog is called in the DIALOGOPEN message handler.

bulletgoldAdded an ELSE case for setting transaction log table field indices when a table already exists.

Shift (Item library)

bulletgoldMoved the code from openModel to OpenModel2 so all Reliability blocks will need to have their openmodel done before receiving a message from the Shift block.

Throw Item (Item library)

bulletgoldFixed that if a Throw Item block had not been set up yet and you click on its dialog, the animation of the label could be wrongly updated.

bulletgoldFixed the issue where sometimes the Throw Item could not find the Catch Item block and no error message was sent, simply the dialog of the block would open with no explanation. Now the dialog will only open if there has been an error message set before.

Transport (Item library)

bulletgoldFixed the getting flag so it happens after the return.

Unbatch (Item library)

bulletgoldMust check after call to PullItems in On ItemOut message handler to make sure we placed an item on the output connector before sending a response to NEEDS.

Activity, Batch, Catch Item, Convey Item, Equation(I), Get, Queue Equation, Queue, Red(I), Resource Item, Set, Transport, Workstation, Write(I) (Item library)

bulletgoldIf Change item animation using property was selected as the Item animation attribute, is wasn't part of the tracking attribute system. It has now been added to the system so the Executive block can know about it.

Data Import Export (Value library)

bulletgoldCleaned up the call sequence for setting up Excel objects in XL_populateNamedRangesPopup and XL_populateTableNamesPopup.

bulletgoldFixed a problem with named range popup not retaining popup settings by passing g_internalEvent as an argument in the call to DIEmsg_onXL_RangeInputType_POP in the XL_RangeInputType_POP message handler.

bulletgoldReplaced existing GUID for ADO COM DLL so it will work with 64-bit COM DLL.

bulletgoldHid the dialog checkbox for using an embedded object.

bulletgoldAdded a condition in DIE_refreshExternalfieldListTable to ensure that XD_TableName_prm is blank before exiting from the procedure.

Equation (Value library)

bulletgoldoVarsOut_NumCons was being used in a for loop to access table arrays. This was not correct as there will always be at least 1 even if the connector is hidden. Consequently, when dealing with table arrays, oVars_NumTableRows must be used.

Lookup Table (Value library)

bulletgoldIf the time scheduled in a table was the same in 2 consecutive rows, the block would think it was time to repeat the schedule. It has been corrected.

bulletgoldProblem fixed that when DISCRETE_OUTPUT + reset + time to reset + data had an entry for time to reset the row in Data was skipped.

Read & Write (Value library)

bulletgoldIf a whole row is being read whole row, the reference point has to be results_StartCoordinate_prm – not "1";

bulletgoldEmbedded objects are no longer supported in ExtendSim 10.

Scenario Manager (Value library)

bulletgoldAllow row=-1 to accommodate scenario table headers row click events in the DIALOGCLICK message handler.

Equation-Based blocks in the Value library

bulletgoldCorrected RCC Functions.h for equation-based blocks.

Convey Flow (Rate library)

bulletgoldTo avoid a loop, the clock needed to be advanced if lrNextEvent==CurrentTime. In some cases of currenttime if events are very close or very large, if could happen that currentTime==NextTime in it would get into an infinite loop.

bulletgoldFor improved accuracy, fixed an issue where it might not test if next the event is too close to current time.

bulletgoldIt was possible to have a Conveyor content of 0 (due to precision) while still having product in a portion that would ocassionally create loops in a current event. To remedy this problem, when the Tank content is 0, the portions are emptied.

bulletgoldsrLastTime_Calculation needed to be set up as StartTime rather than 0 and it needed to know if a first calculation had already been made or not. Otherwise, a connected block could ask at starttime for the content of the block, but it would get -10 because first calculation had not been done yet and if (srLastTime_Calculation>=CurrentTime) prevented the calculation from happening.

bulletgoldWhen content is calculated for each event, we could be in a situation where the on simulate event would occur before the blockreceive2 message handler. It created an error in the simulation and a case in which the exit layer already emptied without going through blockreceive2.

Valve (Rate library)

bulletgoldCorrected an issue that might occur when pasting a Valve block from one model to an empty model, the String lookup for advance status was not being updated leaving the first column of the advance status empty.

 Start Node (Reliability library)

bulletgoldRemoved the valuesIn connector error checking in StepSize. In the case where a user might be running through different scenarios with the RSM block, event cycles settings may legitimately change for wear, cycles, and schedule.

bulletgoldCorrected an issue that might happen when removing an event cycle by hand via the Event Cycles tab. evtReg ID's where not getting recycled so evtReg ID's were constantly growing.

bulletgoldChanged how occLog and reports are managed across multiple runs because simulation runs were slowing down when occLog got too big.

bulletgoldIn occLog, we changed the ID field to not be a unique record ID field in order to speed things up.

bulletgoldFixed a bug with data management for the event log.

bulletgoldCorrected issues in SD_EventsTbl_BlockNum_Get() and SD_IntsTbl_BlockNum_Get() that were holdovers from when ExtendSim switched from block numbers as ID's to unique integers as ID's.

bulletgoldFixed bugs in RBD_DB_EvtStatusTbl_Init() and EVT_CES_Table_FillOut(). The RBD_DB_FI_EvtStatusTbl_Node field was missing the ID value.

 Component, End Node, & Start Node (Reliability library)

bulletgoldThe around me tables were displaying block numbers instead of Node ID's. This has now been corrected.

 All blocks in the Chart library

bulletgoldThe minimum and maximum for axis is now properly kept in between runs.



Application • New and Improved Features

Block Structure

bulletgoldUpdating hierarchical blocks on open models now has a "Please wait…" dialog so you can see its progress.

bulletgoldNavigators now update correctly when changing models.

bulletgoldMore windows now remember their positions when reopened.

bulletgoldImproved stopping model runs that would continue when the Stop button was pressed or abort functions were called.

bulletgoldThe simulation status bar now reports the correct number of runs if the simulation is stopped or aborted.

bulletgoldFixed simulation message order so it is the same as ExtendSim 9, but with additional message handlers.

bulletgoldSuccessive randomized seeds (seed 0) are now different no matter how closely in time they are created.

bulletgoldPasting a model with an Executive block over another model no longer crashes.

bulletgoldChanged qt.conf file so changing the Windows settings for screen resolution and zooming works better.

bulletgoldAdded more color to improve the visibility of selected text and other objects.

bulletgoldFixed a bug where clicking Help opened the wrong block's Help.

bulletgoldImproved the wording for several error messages and dialogs.

bulletgoldAdded warning, and an option to Open or Cancel, when opening a model that had been created or saved in a newer release

Includes • New

CHART_DATA_Management v10.modl (Chart library)

bulletgoldReplaced the dialog for a multi-run trace: Removed checkboxes and replaced with options per the Trace For Run column.

bulletgoldImproved code: Added a new function which returns if data can be collected by looking at disable recording and window recording options.

bulletgoldImproved scaling: Found a more elegant number for scaling limit.

bulletgoldOption changed: Replaced NoResetOnConsecutiveRuns_chk in Scatter and implemented it in the Histogram with additional options on the Run column.

bulletgoldOption changed: Replaced NoResetOnConsecutiveRuns_chk in Scatter and implemented it in the Histogram with additional options on the Run column.



Includes • Fixes

Flow v10.h & Flow constants v10.h (Rate library)

bulletgoldPropagation starving and/or blocking the Convey Flow block is now treated as a Tank and or an Interchange. Limitation is not necessarily both ways.

bulletgoldCorrected an issue with block/starve propagation in cases where:

• An external message comes to a variable connector x and needs to be sent back to the other branches.

• And in the case where another branch y receives another external message.

The branch x now properly propagates this second message by differentiating cLIMITING_TO when it comes from an Executive block or when it comes from within the block itself.

bulletgoldThe siFlowLP_E list tells which blocks are responsible for blocking/starving the flow. Instead of removing blocks from the list while being treated, they are instead flagged because removing elements of the list caused problems by deleting information that is needed in a future section which limits the flow.

Flow solver LP_Solve v10.h (Rate library)

bulletgoldThe siFlowLP_E list tells which blocks are responsible for blocking/starving the flow. Instead of removing blocks from the list while being treated, they are instead flagged because removing elements of the list caused problems by deleting information that is needed in a future section which limits the flow.

bulletgoldImproved the error message that informs which block is linked to a specific section.

Tank functions v10.h (Rate library)

bulletgoldCorrected an issue with block/starve propagation in cases where:

• An external message comes to a variable connector x and needs to be sent back to the other branches.

• And in the case where another branch y receives another external message.

bulletgoldThe branch x now properly propagates this second message by differentiating cLIMITING_TO when it comes from an Executive block or when it comes from within the block itself.

DBN Start Node v10.h (Reliability library)

bulletgoldFixed a network builder bug where the internal database could get confused if the user deleted a node connection in a complicated network.

RBD DBN Procs.h, RBD Procs v10.h, RBD DB Start Node v10.h, RBD DB Indexes Get v10.h, RBD Procs v10.h, RBD DBN Start Node v10.h, RBD DB Procs v10.h, & RBD Prototypes v10.h (Reliability library)

bulletgoldCorrected an issue in which evtReg was not being updated with the correct start node ID for event cycles associated with components during a copy/paste.

bulletgoldFixed selection of a row in the event cycles table in a component block.

RM functions v10.h (Advanced Resource Management)

bulletgoldTotal allocation time is now forced to be equivalent to total busy time.

RM procedures v10.h (Advanced Resource Management)

bulletgoldFor now, in RMprc_updatePoolStatusTime, set total quantity allocation time equal to total busy time.

CHART_BAR_CONN_DataOptions v10.modl (Chart library)

bulletgoldFixed problem that would sometimes occur when liNewSeriesSize and/or liNewCategoriesSize would remain at -1 (no change), it would cause an error.

CHART_CONN_VariableInputConn v10.modl (Chart library)

bulletgoldCorrected an issue that might occur when a point that was identical to its previous one was put on a chart, it was not writing the extra point. The receiving message flag was not resetting to false and cancelled the recording of points from there forward.

CHART_DATA_Management v10.modl (Chart library)

bulletgoldIf time changed, but liY_ValueHasChanged hadn't, and you selected the last point on the chart, the point would sometimes be ignored as there was some missing code.

CHART_DISPLAY_options v10.modl (Chart library)

bulletgoldScaling is now done during a simulation run only after 2 points have been drawn on the Graph. No scaling of points any earlier as it was too much of a guessing game.

bulletgoldScaling during initsim is done differently if it's a Bar or Line Chart.

CHART_TRACE_CreateAndAddNewPoint v10.modl (Chart library)

bulletgoldThe minimum and maximum for axes is now remembered between runs if necessary.

RPM dialog v10.h (Report library)

bulletgoldBlock names are now filtered by those which have a Results tab when building a list of unique block names in a block filter types table.

Block location utils v10.h

bulletgoldIf error message during open model then it aborted the initialization, abort has to be replaced by return.

CONA_Manage_ConnectorArray v10.modl

bulletgoldChange from an error message if failed function to return -1, it allows more flexibility in the timing of some calls.

RP procedures v10.h

bulletgoldAdded an ELSE case for setting transaction log table field indices when a table already exists.

If the two ways of counting product doesn't match, this block will stop the simulation and give an error message. If the difference is negligible and you would prefer the simulation to continue even with a mismatch, you can use the Disable quantity checking checkbox to disable automatic checking.

Valve and Flow (Rate library)

bulletgoldFor debugging purposes. we've added the ability to keep going in recursive mode to be able to follow the recursive loop if debugger code is turned on in the block.

Event Builder (Reliability library)

bulletgoldAdded Edit Instances Table and Commit Instance Changes buttons to help users change event cycle instances for all RBD's in the model.

Start Node (Reliability library)

Information (Item library)

bulletgoldFixed Animation so when toggling between Off and On, if simulation is not running, the animation would not turn back on.

Resource Manager (Item library)

bulletgoldAdded logic in RMmsg_onShiftSchedule to properly account for status changes of allocated resources that are not residing in Activity blocks when shift changes occur.

bulletgoldWhen a resource is transitioning to busy and is currently attached to an item in an Activity block, pending status is set to idle.

Resource Pool (Item library)

bulletgoldFixed a problem with shift status transitions and resources not yet released when the pool goes off-shift and the input connector receives an input to change the resource quantity of the pool.

Select Item Out (Item library)

bulletgoldCorrected the issue that GotItem was not initialized to 0 at beginning of the simulation, then the first call in itemIn could block any item going through.

Convey Flow (Rate library)

bulletgoldWhen creating the LP constraint, the block should not only consider the flag siConveyorIsFull, but should also look at the effective content of the block. At any given time, the block could be full with an output rate greater than the input rate. The flag for conveyFlowFull is then False, but logic should consider it full; otherwise it's at risk to accept more flow than possible in the block.

Event Monitor (Utilities library)

bulletgoldTo get the number of event posting blocks in a model call GetDimension() on the TimeBlocks[] array instead of the TimeArray[] array.

Queue Tools (Utilities library)

bulletgoldOpening a model created prior to ExtendSim 9.3 or ExtendSim 10 would remove data from InitAttribsValue_ttbl. Data needed to be recovered from a model in older version.
