**v7.31.114** WTNV114 - Water flow on a saturated porous medium
=================================================================

**Summary:**

The hydraulic behavior of a saturated porous medium is studied. Nine models are carried out: two two-dimensional models (models A and B) and seven three-dimensional models (models C, D, E, F, F, F, G, G, H, I).

The distinction between the models lies in the law of fluid behavior (LIQU_SATU for the A, C, G, H, I and LIQU_GAZ_ATM for the B, D, E, F models).

This test consists in applying a water flow to the upper face of the model and in studying the effect of this flow on the distribution of fluid pressure in the saturated medium. It is an evolving problem.

The first eight models studied are 2D planes (HM_DPQ8) and 3D volumes (HM_HEXA20 or HM_PYRAM13) with linear behavior. The latest model is HM-XFEM.

The reference solution is one-dimensional because it only depends on the vertical coordinate.
