20-sim is a modeling and simulation program that runs under Microsoft Windows. With 20-sim you can simulate the behavior of dynamic systems, such as electrical, mechanical and hydraulic systems or any combination of these.


20-sim fully supports the use of components. This allows you to enter models as in an engineering sketch: by choosing components from the library and connecting them, your engineering scheme is actually rebuilt, without entering a single line of math!

From 20-sim you can export any part of a model as C-code to 20-sim 4C. The complete model hierarchy is exported as well, including the component thumbnails.


To run 20-sim, you need the following hardware and software:

  • A PC with an ethernet connection running·Windows XP or higher.

20-sim can be purchased directly from this website.
