v7.33.113 WTNA113 — Modeling the injection of incompressible water into a saturated medium

Summary:

A saturated cylindrical bar is studied at the top of which a flow is injected. The associated law of fluid behavior is of type LIQU_SATU. The modeling is hydromechanical (HM). The fluid is incompressible and the medium is infinitely rigid. It is therefore a stationary problem involving an analytical solution. The objective of this test is to validate the correct consideration of a hydraulic flow boundary condition in the case of axisymmetric modeling.
