v4.22.100 TTNL100 - Non-linear heat source, homogeneous solution in space

Summary:

This test verifies the thermal calculation in the presence of a non-linear source load, depending on the temperature.

The reference solution is analytical. The part considered in the models consists of a single element whose dimensions do not matter a step in the solution.

The following meshes are checked:

• Modeling A:

  • TRIA3, TRIA6, QUAD4, QUAD8 and QUAD9 for modeling PLAN,

  • TRIA3, QUAD4 for modeling PLAN_DIAG,

• B modeling: PENTA6 for 3D modeling

Since the temperature is homogeneous in the element, the calculation can be considered as 0D.
