**v1.01.178** ZZZZ178 - Validation of the thermo-mechanical chaining methodology in HPC
========================================================================================

**Summary:**

This test validates the thermo-mechanical chained calculation methodology in HPC.

The calculation involves the following steps:


* parallel reading of the MQ quadratic mesh
* creation of the ML linear mesh using the CREA_MAILLAGE command
* resolution of the thermal problem on ML
* parallel projection by subdomain of the temperature field to MQ by the command PROJ_CHAMP
* definition of mechanical material taking into account the field of control variables
* resolution of the mechanical problem on MQ

The standards of the various fields are compared with sequential resolution.

This test includes two models:


* modeling A: D_ PLAN
* B modeling: 3D with thermal loading by AFFE_CHAR_THER
* C: 3D modeling with thermal loading by AFFE_CHAR_CINE
* D and E modeling: like B modeling but replacing the chain with a weak MPI coupling.

We emphasize the fact that the creation of the linear mesh ML by the command CREA_MAILLAGE by the command is **indispensable** for the proper functioning of the parallel projection by the command PROJ_CHAMP.

This documentation is deliberately brief.
