L modeling
==============

Characteristics of modeling
-----------------------------------

HEXA8_D

We mesh only half the thickness of the wall for reasons of symmetry; the modeling is done under a height and a thickness :math:`h=1.0` with a single layer of elements.

We use the 3D_ DIAG modeling applied to HEXA8, which corresponds to the lumping of the thermal mass matrix.
