v4.23.100 TTLP100 — Transient thermal wall exchange

Summary

The linear or non-linear transient thermal response of two plates separated by a gap in which heat transfer takes place is calculated. The problem is 2D but the boundary conditions mean that the temperature depends only on the x-axis and on time. The steady state is rapidly reached, which can be calculated analytically.

The test makes it possible to verify that the terms related to heat exchange between 2 walls have been taken into account.
