Hi, when I set the formulation to MPC under Frictional contact, the system highlights the row of "Formulation" and shows a question mark in front of "Contacts", like what you would get in "Geometry" without defining a material. I tried and found that this is the case for Frictional, Frictionless, and Rough. It's fine for Bonded and No Seperation but those 2 are not what the contacts should be. Any thoughts on that?

On the other hand, the following picture indicates the boundary conditions of the model for your information. Thanks!
