**v7.31.123** WTNV123 - Triaxial fixed-suction test with the Barcelona model
==================================================================================

**Summary:**

This test validates the integration of the Barcelona model [:ref:`r7.01.17 <r7.01.17>`]. The present test carried out in modeling A, in hydro-mechanical coupling (modeling HHM), includes two mechanical loading paths, the capillary pressure being fixed at a non-zero value (unsaturated test conditions):

* An isotropic compression path.
* A triaxial compression path.

The modeling is carried out on a hexahedral 3D element.
