About 20-sim
20-sim is a modeling and simulation program. You can simulate the behavior of dynamic systems, such as electrical, mechanical and hydraulic systems or any combination of these. It utilizes the bond graph graphical representation of models, allowing for flexible modelling and simulation. The differential equations of a model can be exported into various tools, like C, Matlab and Simulink for further processing/analysis.
Another nice feature is the 3D modelling toolbox, allowing easy and quick 3D animation of mechanical systems.
