Analytical Chemistry


Professor Emeritus Edward Voigtman

Univ. Of Massachusetts - Dept. Of Chemistry

Amherst, MA USA

LightStone allows you to model the quantitative behavior (including real noises) of modern spectrometric instrumentation such as UV-vis & IR spectrometers, optical polarimeters, etc. The libraries contain more than 300 blocks, offer polychromatic modeling up to 100,001 wavelengths, and fully implement the entire Jones & Muller optical calculi. There are numerous blocks pertaining to statistics and even a genetic optimization block.

Prof. Voigtman's textbook Limits of Detection in Chemical Analysis details methods for computing valid limits of detection in chemical analysis and demonstrates various theories using the Lightstone module.

Lightstone may be used with any of the ExtendSim packages.



The BioQUEST Library

The BioQUEST Curriculum Consortium (BQCC)

Beloit College -- Biology Department

Beloit, WI USA

The BIOQUEST Library is a peer-reviewed publication that contains more than 70 tools, simulations, databases, and other resources used in undergraduate biology. The Library represents a collaborative effort to provide opportunities for students to engage in problem posing and problem solving in a variety of biological investigations. Students are encouraged to develop strategies for:

  • Experimental design
  • Acquisition and analysis of large data sets
  • Effective peer persuasion at all stages of scientific investigation

BioQUEST may be used with any of the ExtendSim packages.

Distribution Fitting


Geer Mountain Software Corporation

South Kent, CT USA

Stat::Fit statistically fits input data to analytical distributions. The Auto::Fit function automatically fits continuous and discrete distributions, providing relative comparisons between distribution types. The Export function translates the fitted distribution into the specific form for ExtendSim. The distribution viewer allows interactive display of distributions, providing for quick no-data representations.

This companion product is included in ExtendSim Pro and may be added to any other ExtendSim package.


Engineering of Complex Systems


John R. Clymer and Associates

Fullerton, CA USA

The OpEMCSS (Operational Evaluation Modeling for Context-Sensitive Systems) module provides the ability to examine important elements in a problem space and allows the formulation of alternative solution concepts. OpEMCSS contains a forward chaining, expert system controller that can implement both crisp and fuzzy rules. Plus, it applies reinforcement learning to discover optimal rules to manage system operation.

You MUST own ExtendSim Pro to use this module.


Process Industries

Frontway AB

Norköpping, Sweden

PaperFront is a material and energy balancing software, with the ability to act as a digital twin whatever quality targets you have. PaperFront is developed for the process industry, focusing on the pulp- and paper industry (no exclusions). The software is uniquely designed for complicated production processes, block-building, and multivariable management.

PaperFront is being used to optimize material flow and product quality, environmental studies, and energy management. The software is also being used for production planning (on a 7-day basis) and corresponding power consumption prediction.

The software manages full-dynamic simulations, chemical components, solids and solubles, custom components, steam and moisture, physical properties, quality variables, and more. DCS connections are available.

PaperFront contains only four (4) libraries, with 50 blocks that provides functionality for all types of uses:

  • Process industry simulations with blocks such as pumps, chests, heat exchanger, mixing/splitting functions, and more.
  • Pulp and paper industry with blocks such as disc filter, headbox, wire, and more.
  • Tools for managing large simulation models with different scenarios.
  • Standard ExtendSim libraries work smoothly together with PaperFront.

PaperFront is an easy to use software module with help tools such as video-tutorials, demo-models, and individual help-texts to all blocks. FrontWay also offers education in the software and consulting services related to simulation. All simulation models and custom blocks go through an internally established quality check before delivery.

ProcessFront is a light version of PaperFront with focus on the general process industry.

PaperFront/ProcessFront may be used with any of the ExtendSim packages.
