Hi Roy,
Thank you for your reply. I think I will go with two separate equation systems one on each mesh. The problem I am trying to solve is a two half plane and in between it is governing by a friction model, and the friction contact is enforce by a method "TSN" (Traction Separation nodes). Say I have two half plane (mesh_pos,mesh_neg), so the mesh_pos 's bottom layer is gonna to be applied some traction , and the mesh_neg' top layer is gonna be applied some traction to enforce the jump condition and also the friction law. So what I need is to have these two separate EquationsSystems(System for mesh_pos, System for mesh_neg), two parts are solved separately but at the same time step, the only interaction is through the traction at the separate nodes.
