**v1.01.292** ZZZZ292 — Basic validation of SANS_GROUP_NO_FR
==================================================================

**Summary:**

This test validates the SANS_GROUP_NO_FR feature specific to touch-friction in continuous formulation:


* two identical cubes are brought into contact with friction


* a symmetry condition is applied to one of the faces of each of the cubes


* the redundancy with the friction conditions caused by this boundary condition is eliminated thanks to the keyword DIRE_EXCL_FROT whose proper functioning is being tested

The solution on the go is analytical.

Modeling A:


* 3D modeling with continuous formulation
