**v4.22.302** TTNL302 - Infinite wall subject to a constant flow 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 five models, one plane, the other four solid.

The features tested are as follows:


* flat thermal element,


* volume thermal element,


* non-linear transient thermal algorithm,


* variable properties,


* limit condition: imposed flow.

The advantage of the test lies in taking into account variable properties (thermal conductivity and volume heat).

The results are compared to an analytical solution.
