In [A]LM methods, we rely on computed tolerances to decide on the slip/stick/open dispatch. Those are strongly geometry related in their estimation of the local inverse of the stiffness from left/right neighbors. Originallym the method was implemented with hexahedron/quad mixed dimensionality assumption.
Now we are running with mixed and tetra meshes. The original assumption tends to render a stiffer system. This PR propose dispatch with old behavior for Hex/Quad and right angle Tetra/Triangle approximation for triangles. (Extensible if needed_
