The contact penetration, the solver assumes that the solution is converged when all the convergence criteria are met and when the penetration is within the tolerance (default is 10% of underlying element size). So, here are a couple of things that one can try: – Refine the mesh (especially on the contact side) – increase the contact normal stiffness (this may cause convergence issues, I’d say use 0.1 if the default does not work). – decrease the contact penetration tolerance (you can find this under the contact details, set it to a factor of 0.05 to reduce the tolerance to 5%) – Use normal Lagrange formulation (this will result in the least penetration but it can be a bit expensive).
