2. Modeling A#
2.1. Characteristics of modeling A#
D_ PLAN_HH2SUDA modeling, this modeling corresponds to finite volume modeling (VFDA). Coupling LIQU_AD_GAZ. A mesh composed of 200 QUAD8 elements is used.
2.2. Results#

The gas pressure and capillary pressure profiles are plotted at different times:

It can be seen that gas pressure increases up to 100,000 years and then decreases. It is also observed that the gas diffuses into the domain over time.
It can be seen that desaturation begins at 100,000 years of age (when capillary pressure becomes positive). This means that the gas is initially only transported by dissolution/diffusion. The results are what we expected.
2.3. Tested values#
This test case has no reference value, so we make it a non-regression case. Tests are carried out on 6 values:
