v7.32.122 WTNP122 - Modeling of a weakly non-linear bar saturated with compressible gas (monophasic flow) subjected to a pressure shock

Summary:

The purpose of this test case is to validate:

• the finite volume diagrams developed for the modeling of two-phase flows.

• hydraulic modeling saturated with finite elements D_ PLAN_HS

The two-phase problem will here be degenerated into a monophasic gas problem whose analytical solution is known. This is the one-dimensional modeling of a gas-saturated bar subjected to a pressure shock.
