u3.23.02 AXIS_FOURIER thermal modeling

Summary:

This document describes for thermal AXIS_FOURIER modeling:

• 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 modeling.

Modeling AXIS_FOURIER (Phenomenon: THERMIQUE) corresponds to finite elements whose support meshes are plane and make it possible to model the longitudinal section of pieces of revolution around the OZ axis (in cylindrical coordinates) subject to boundary conditions whose spatial distribution is broken down into a series of FOURIER around this axis.
