Principle of the test
================

The principle of this test consists in defining, using the same mesh:


* a thermal model enriched with MODI_MODELE_XFEM/FISSURE;


* a mechanical model enriched with MODI_MODELE_XFEM/FISSURE, with the same cracked geometry as for modthx;


* a mechanical model enriched with MODI_MODELE_XFEM/MODELE_THER, by "copying" modthx.

Once these 3 models are created, we perform several checks that require the use of python, and the execution of the test in PAR_LOT = 'NON'. These checks are as follows.


1. By using the procedure IMPR_CO/NIVEAU =-1 [:ref:`U4.91.11 <U4.91.11>`], we ensure that these 3 rich models all contain the same number of objects.


2. We then ensure that the description of each object '. CELV 'of the cham_elem contained in the 3 sd_modele_xfem remain identical from one model to another. This description corresponds to NIVEAU =-1 in IMPR_CO
