M modeling
==============


Characteristics of modeling
-----------------------------------

A 3D modeling for solid elements is used with the CONTINUE method for the treatment of CONTACT with MORTAR pairing and LAC cutting.

Tested sizes and results
------------------------------

The contact pressure is tested on all the master and slave contact surfaces, as well as the components of field CONT_ELEM.
