Modeling A
====


Characteristics of modeling
----

Modeling A corresponds to the TP statement. It only includes the first thermal calculation (without diagonalization of the thermal mass). The mesh has 3 QUAD4 meshes in the thickness (mesh GIBI).

Characteristics of the mesh
----

6 meshes

The useful edges for boundary conditions are defined by the cell groups:


*   :math:`\mathit{ECHANGE}` (left edge)


*   :math:`\mathit{HAUT}` (top edge)


*   :math:`\mathit{BAS}` (bottom edge)

**Note**:

*This modeling only includes a non-regression test. It is the starting point of the TP, intended to improve modeling (cf modeling B) .* *On the evolution of the temperature in the middle of the cylinder as a function of time, and the temperature distribution at* :math:`t\mathrm{=}\mathrm{4s}`\ *. We note (see red curves, with square marker in the following figure) that we exceed the temperature of* :math:`100°C` *, which is not a physical step. This characterizes a lack of respect for the principle of maximum.*
