v7.31.127 WTNV127 —Desaturation of an airless porous medium (3D modelling_ THV)

Summary:

A porous medium is heated whose pores are filled with a mixture of water and water vapor. The initial liquid saturation is \(\text{50\%}\), the load is a uniform heat flow at the edges of the domain. The modeling done by a single cubic element corresponds to the modeling of a homogeneous problem in space.

The reference solution is an approximate analytical solution.
