J modeling
==============

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

TETRA4_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. Each cube is divided into 5 tetrahedra.

We use the 3D_ DIAG modeling applied to TETRA4, which corresponds to the lumping of the thermal mass matrix.
