I have a simple model to show my problem. The cantilever beam can move to down only. The other direcion (red) is limited by a body.
So there is a contact interface between the body and the beam. I would like to complate a modal (and later a dynamic) simulation but theye dont allow the contact interfaces. (Free and bonded only). I think, the limitation has an effect on the modal analysis. What could you suggest to solve this problem?
