,and sir, also I am going to ask you one more thing to be clarified. For a frictional/frictionless contact, is there an option to completely remove the penetration convergence between the target and contact faces? I mean if the nodes of the target face and contact face come into contact with each other during the solution, then I want them to apply a displacement constrain between those nodes in contact and work as like MPC. Is it possible to do something like this?
