v7.31.125 WTNV125 —Calculation of capillary rebalancing of a bi-material

Summary:

This test case corresponds to the simplified hydraulic study of a slice of land in a storage site. Two materials are considered: an engineered barrier (\(\mathit{BO}\)) and a geological barrier (\(\mathit{BG}\)). Initially \(\mathit{BO}\) is desaturated and \(\mathit{BG}\) saturated. Here we study the capillary rebalancing of the whole (which corresponds to the restoration of the barrier created by the geological barrier).

This test case is similar to the wtna100 case (in axisymmetric version).
