I am trying to build a model for the dog clutch with Simscape multibody as shown in the below figure. each side can rotate independantly, and the dog teeth contact each other. the model is translated from solidworks using Multibody link. To model the contact, I am using the spactial contact force block. I tired to run the model and rotate one dog side but it penetrate the other one.
According to MATLAB help the geomtry export should be turned on and 'export entire geometry' can be seen. However, In my case, I see only the option 'convex Hull'

Just summarize the discussion into the answer.
Have fun with your modeling!

Contact force only works with Convex Hull at this moment. See Documentation page here:
I think it's possible to separate the teeths as individual solid blocks. This way they'll all be sufficiently described by convex hulls. If possible, separate the teeths from the base in CAD so they appear as individual parts in Multibody. You may then do the convex hull thing with each teeth. Try it with a small number of teeth and before going to all 30 of them.
