This version of ExtendSim is designed for students building models for classwork. It allows students to:

  • Build and save small (75 blocks or less) models for a limited time (180 days).
  • Run larger models, change parameters, view simulation results, and save the changes.
  • Print model worksheet, block dialogs, and so forth.


However, there are some limitations:

  • The models you build are limited to a maximum of 75 blocks.
  • The model-building capability expires 180 days after installation. (Note: model-running capability does not expire.)
  • You may not use scripting or ActiveX automation to run or construct a model
  • This version is licensed only for your personal use on a single computer.
  • The Student version may not be used for commercial purposes, including consulting or research that is subsidized by a private or government enterprise.
  • There is no upgrade path and technical support is limited to installation questions.

Operating System Requirement

Windows XP, Vista, 7, 8, 10, or 2000

Hard Disk Space 

300 MB (400 MB for ExtendSim Suite)


512 MB; 2 GB RAM recommended

Central Processing Unit

Since simulation is processor-intensive, we recommend that your computer have a powerful central processing unit (CPU). Furthermore, as release 9 does not support multiple processors, fewer cores with faster processing speeds will execute simulations faster than more cores.

Additional Requirements

For ExtendSim Suite add 100 MB hard disk space and a 3D hardware accelerator card with at least 64 MB RAM
