A defect affecting operation with a low possibility of significantly affects.

An enhancement to the software.
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.
