v7.31.111 WTNV111 — Heat flow on a saturated porous medium

Summary:

A three-dimensional thermal problem in a saturated porous medium is considered.

This test consists in studying the effect of applying a temperature flow to the upper side of the model on the temperature distribution in the element. We limit ourselves to studying the first step of time. We block the pressure and the movements.

The models studied are \(\mathrm{2D}\) plane (DPQ8 and DPTR6) and \(\mathrm{3D}\) solid (HEXA20) with linear behavior.

The reference solution is then the solution of a pure thermal calculation (THER_LINEAIRE) with Code_Aster.
