**v4.01.007** TPLA07 - Orthotropic Hollow Cylinder
=================================================

**Summary:**

This test is the result of the independent validation of version 3 in linear stationary heat.

It is a 2D axisymmetric problem represented by two models, the first three-dimensional, the second 2D axisymmetric.

The advantage of this test case is to test an orthotropic material subjected to various boundary conditions (imposed flow, convection, linear variation of external temperatures).

The results from this test case are compared with those provided by VPCS.

In addition, this test validates the calculation of thermal energy for an orthotropic material on 2D elements. To do this, two calculations are made in addition to the one with the orthotropic material:


*
    * a calculation with isotropic material (keyword THERde DEFI_MATERIAU) used as a reference


    * a calculation with isotropic material but using the THER_ORTH keyword from DEFI_MATERIAU validated by the first calculation.

For the really orthotropic calculation, a reference NON_REGRESSION will be used.
