Hello Jan,

I am very interested and am in the process of making contact. I very much appreciate your work on this. Thank you.

Randy

The specific error you mentioned will be fixed in next release but, we looked at the library and found some problems with it, like the fact that the following equations in SphericalContactSurface:

connect(shape.frame_a, frame_a);
connect(shape.frame_a, contact_a.frame); 

and in one of its inherited class PartialContactSurface:

connect(frame_a, fixedFrame.frame_a) ;
connect(fixedFrame.frame_a, body.frame_a);
connect(frame_a, contact_a.frame);

create an over-constrained connection set.

There are dedicated Modelica functions to solve this issue, therefore I suggest you report it to the library developers.

Hello George,

I came across your old post since I'm having the same problem using the IdealizedContact library. I've contacted technical support at Wolfram and their response is it's not a supported library. Did you ever find a way to use it?

Randy
