**v4.22.303** TTNL303 - Infinite wall subject to a temperature jump with variable properties
=============================================================================================

**Summary:**

This test is the result of the independent validation of version 3 in non-linear transient heat.

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

The features tested are as follows:


* flat thermal element,


* volume thermal element,


* variable thermal conductivity,


* non-linear transient thermal algorithm,


* limit conditions: imposed temperature with jump.

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