v6.03.173 SSNP173 - Contact between two concentric spheres

Summary:

This problem corresponds to a quasistatic analysis of a mechanical problem with frictionless contact whose analytical solution is known. Here, we are particularly interested in integrating contact terms using the Mortar Local Average Contact (LAC) method on a curved surface. The meshes are incompatible.
