v4.21.301 TTLL301 - Heat transfer in a bar with imposed temperature (sine wave)

Summary:

This test is the result of the independent validation of version 3 in linear transient thermal.

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

The features tested are as follows:

1. flat thermal element,

2. volume thermal element,

3. transient thermal algorithm,

4. limit conditions: sinusoidal variation in temperature imposed over time.

The advantage of the test lies in taking into account the variation in temperature imposed over time and the geometric discretization.

The results are compared to those provided by NAFEMS.
