400 Merging, Diverging, and Routing Flow
Throwing flow and catching flow remotely
Group filter
Each block with throw or
catch capabilities can be
added to a throw/catch
group. Groups can be cre-
ated or selected through
the group popup menu
found in the sending and
receiving blocks. When this popup is blank, the block does not belong to a group. When a block has been added to a group, its throw/catch options are limited to the blocks currently in that group.
Block type filter
By default, the block types a throwing block can connect to include both Catch Flow and Merge blocks and the block types a catching block can connect to include by Throw Flow and Diverge blocks.
Defining a Group
• For throwing blocks, the list of blocks to select from can be narrowed to only Catch Flow blocks or only Merge blocks.
• Forcatchingblocks,thelistofblockstoselectfromcan be limited to only Throw Flow blocks or only Diverge blocks.
Only unconnected blocks filter
Block type filters for a Diverge block
This filter narrows the selection of possible blocks to only those blocks without an established throw/catch connection.
Examples of throw and catch connections
The two example models that follow show how to use catching and throwing in a model. The first model uses Throw Flow and Catch Flow blocks; the second model uses a Diverge block.
Catch Flow and Throw Flow model
The Catch Flow and Throw Flow model shows two lines, one above the other. They produce identical results even though the flow connections have been created differently:
• Thetoplineusesnormalflowcon- nection lines to connect Valve A to Valve AA.
• Thebottomlineusesathrow/catch connection to connect Valve B to Valve BB. In this line, the flow is sent remotely by a Throw Flow block and received by a Catch Flow block.
