Adding contact blocks to a model imported from Inventer into Simscape
7 views (last 30 days)
I have imported an Inventer CAD model into simscape multibody and added contact blocks to the model, but the contact simulation does not work.
I don't think there is a problem with the contact blocks because I added them in Simscape after importing.
So I think the problem is with the solid blocks. Here are the imported solid blocks and the common solid blocks used in Simscape.

What are the differences between the two solid blocks, and what are some tips and tricks for adding contact blocks to an imported model for simulation?

You need a spatial force contact block taking in both geometries to resolve the contact. Modeling Contact Force Between Two Solids - MATLAB & Simulink (mathworks.com)
If the contact is not captured, it could be caused by a solver resolution issue (time step does not get small enough to capture the contact) or by that the convex hull approximation of the bodies leads to a non-realistic contact event.
If the problem persists, I'll recomend contacting our Technical Support to sort the root cause of the problem.
