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.
