5. C modeling#

This modeling is exactly the same as modeling A. The only difference is in the mesh: the HEXA8 of mesh A are cut in TETRA4.

5.1. Characteristics of modeling#

We use the 3D modeling of the THERMIQUE phenomenon.

5.2. Characteristics of the mesh#

The mesh includes 30 TETRA4 meshes.

5.3. Tested sizes and results#

We first test the values of the classical degrees of freedom TEMP and Heaviside H1 of the temperature field at the output of the THER_LINEAIRE operator, at the nodes located just below (4 knots) and above the interface (4 knots).

We then test the value of the degree of freedom TEMP of the temperature field at the outlet of POST_CHAM_XFEM, at the nodes located just below and above the interface.
