Hi everyone.
I want to simulate the rotation of wheel in COMSOL in the multibody dynamics interface. The tire is made of hyperelastic rubber, but hyperelastic model is not available in multibody dynamics interface so I decided to use solid mechanics physics to build the material modal.
I have done some searching to find solution about the coupling of the 2 physics. Most of them are talking about the attachment setting which is available in both of the physics. However I don't truly understand how to set the attachment?
Related to your query, I would like to suggest you : https://www.comsol.com/blogs/coupling-structural-mechanics-interfaces/

and https://doc.comsol.com/5.4/doc/com.comsol.help.mbd/MultibodyDynamicsModuleUsersGuide.pdf
Muhammad Ali Thank you very much for your suggestion. I have already achieved the coupling by setting the dependent variables to be the same between the two physics and form a union between the rim and the tyre entities.
