**u3.13.02** Mechanical AXIS_FOURIER modeling
=================================================

**Summary:**

This document describes for mechanical AXIS_FOURIER modeling:


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


* the related support meshes,


* the loads supported,


* non-linear possibilities,


* test cases implementing modeling.

Modeling AXIS_FOURIER (Phenomenon: mechanical) corresponds to finite elements whose support meshes are plane and make it possible to model the longitudinal section of pieces of revolution around the axis :math:`\mathit{OY}`, (in cylindrical coordinates :math:`(r,z,\theta )`) and subjected to loads whose spatial distribution is broken down into series of FOURIER around this axis.
