**v4.22.304** TTNL304 - Infinite wall subject to a temperature jump with variable orthotropic properties
=========================================================================================================

**Summary:**

This nonlinear transient thermal test is similar to TTNL303 except that the material properties are orthotropic.

It is a linear 1D problem represented by two models, one plane and one solid.

The features tested are as follows:


* flat thermal element,


* volume thermal element,


* variable orthotropic thermal conductivity,


* non-linear transient thermal algorithm,


* limit conditions: imposed temperature with jump.

The advantage of the test lies in taking into account variable and orthotropic properties in transient analysis and the variation of the temperatures imposed as a function of time.
