v7.32.115 WTNP115 — Desaturation of an airless porous medium on a unit cell

Summary:

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

The reference solution is an approximate analytical solution.
