v7.31.109 WTNV109 - Hydraulic and mechanical loading of a saturated porous medium

Summary:

A three-dimensional problem of thermo-hydro-mechanical coupling of a saturated porous medium is considered.

This test consists in studying the effect of mechanics and hydraulics on thermal energy. The element is stretched by forcing it to move in the \(z\) direction, hydraulic pressure is imposed on the entire domain and the effect of these loads on the temperature of the model is studied. It is a question of looking at the very weak coupling between poromechanics and thermics. We limit ourselves to the first step of time.

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