K 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.


Characteristics of the mesh
----------------------------


.. _DdeLink__1459_7712239786:

The mesh contains 900 elements of type TETRA4. The meshes of the 2 contact surfaces are incompatible.

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.
