**v6.03.120** FORMA21 - Thermo-mechanical adaptive mesh on a cracked cylinder head
====

**Summary:**

A **thermo-elastic calculation is carried out on a cracked metal yoke** using plane stress modeling (for the mechanical part) and lumped stress modeling (for the thermal part). In accordance with "good practices" for the quality of studies, two distinct meshes are used: linear in thermal and quadratic in mechanics.

First of all, the thermal calculation is carried out (modeling A) on which the :math:`{P}_{1}` mesh is freely converged with a spatial error indicator map (CALC_ERREUR + 'ERTH_ELEM') /refinement-deraffination (MACR_ADAP_MAIL + 'RAFF_DERA') map coupling.

In the second modeling (B), the two meshes are adapted jointly according to the same process during a chained thermo-mechanical calculation. For the free adaptation of the mechanical mesh, use is made of the pure residue indicator 'ERME_ELEM'.

This test case makes it possible to test the non-regression of various coupling error map calculations/refinement-deraffination procedures in thermo-mechanics, and the "pre and post-processing" options for these calculations.
