20sim Viewer 3.6.11 Screenshot

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

20-sim fully supports graphical modeling and gives you the possibility to analyze and design dynamic systems in a intuitive and user friendly way. 20-sim supports the use of components. This helps you to enter models as in an engineering scheme: by choosing components from the library and connecting them, your engineering scheme is actually built without entering a single line of math!

Here are some key features of "20sim Viewer":

· If you select an expression with the mouse pointer, the current value of that expression will be shown.
· A planetary gearbox has been added. it can be found in:
· libraryIconic DiagramsMechanicalRotationGears


Whats New in This Release:

· Code for the sqr-function is now generated successfully
· Code generation for models with dependent states causes no problems anymore
· In the Linear System Editor due to numerical round-off the derivation of bode plots was not correctly performed. This problem only occurred with stiff systems (i.e. systems with parameters varying more than 14 orders in magnitude). The use of a new numerical routine has now solved this problem


Limitations:

· The only restriction is that you cant save your work (it is a viewer).
