Controllab Products 20-Sim v4.0.1.7

0-sim is a modeling and simulation program that
runs under Microsoft Windows. With 0-sim you can
simulate the behavior of dynamic systems, such as
electrical, mechanical and hydraulic systems or any
combination of these.

0-sim fully supports graphical modeling, allowing
to design and analyze dynamic systems in a intuitive
and user friendly way, without compromising power.
0-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 !
