**u3.23.01** Models AXIS, PLAN,, AXIS_DIAG and PLAN_DIAG - Phenomenon THERMIQUE
===================================================================================

**Summary:**

This document describes for thermal models of axisymmetric and plane elements:


* the degrees of freedom carried by the finite elements that support modeling,


* the related support meshes,


* the materials and loads supported,


* non-linear possibilities,


* test cases implementing the models.

Axisymmetric and plane models (Phenomenon: THERMIQUE) correspond to finite elements whose support meshes are surface.

The models AXIS_DIAG and PLAN_DIAG cover the same possibilities as AXIS and PLAN and only differ from them for a thermal calculation where the thermal mass matrix is then diagonalized.
