Hi!

I am still beginner for Comsol. When I attempt to simulate, the steel ball flies away from the circular path. I don't know why.

Thanks for the help

As the ball is in contact with the inside boundaries of the outer path, you need to selectUse inside boundaries for contactforRigid Body Contact 1.

Hope this helps.
