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.
