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

The principle of this test consists in:


1. to define from the same mesh as many enriched models (with the operator MODI_MODELE_XFEM) as many models that can be assigned to this mesh;


2. to ensure, using the procedure IMPR_CO/NIVEAU =-1 [:ref:`U4.91.11 <U4.91.11>`], that the enriched models thus created all contain the same number of fields produced by the options TOPOSE and TOPOFA;


3. to ensure, always using the IMPR_CO/NIVEAU =-1 procedure, that each of these cham_elem is sized in the same way from one enriched model to the next.

These checks require the use of python and the execution of the test in PAR_LOT = 'NON'.
