**v7.31.146** WTNV146 - Validation of a cohesive law model for the hydromechanical case coupled with XFEM
=========================================================================================================

**Summary:**

The aim of this test is to ensure the proper functioning of the "Mortar" type cohesive zone model associated with hydromechanical elements coupled with XFEM.

In this test, we test all the operating regimes of the cohesive zone model for the HM- XFEM elements. The cohesive law used is CZM_LIN_MIX (It is the only one available for the HM-XFEM elements). This test is therefore purely mechanical, all the degrees of freedom associated with the fluid phase are locked at zero. Modeling A is two-dimensional while modeling B is three-dimensional.
