8. F modeling#

This modeling corresponds to the 2D reference problem described on page 2.

8.1. Characteristics of modeling#

We use the PLAN model of the THERMIQUE phenomenon.

8.2. Characteristics of the mesh#

The mesh includes 5 QUAD4 meshes.

8.3. 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 (2 knots) and above the interface (2 nodes).

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.

Finally, we test the value of the TEMP component of the TEMP_ELGA field on the Gauss points located below and above the interface (cf. note page 6).
