When using the penalty enforcement option, the penalty force is simply the contact penetration times the penalty stiffness. For the same geometry but a more/less refined mesh, the contact force will vary, leading to different solutions. The fix is to normalize the penalty parameter by the nodal area. I'll work on this.
