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 graphical modeling, allowing to design and
analyze dynamic systems in a intuitive and user friendly way,
without compromising power. 20-sim 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 !
