3. Modeling A#

3.1. Characteristics of modeling#

D_ PLAN_HH2SUDA modeling. This modeling corresponds to the Finite Volume modeling centered on the edges for mobilities (Fickian terms are centered). The hydraulic coupling law is LIQU_AD_GAZ_VAPE.

3.2. Characteristics of the mesh#

A mesh consisting of 100 QUAD9 elements is used.

3.3. Tested quantities and results#

Tests on 4 nodes at 1 time are carried out first by comparing the results with the analytical solution and a second time by carrying out a non-regression test.
