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.
