4. B modeling#

4.1. Characteristics of B modeling#

This case corresponds to a Richards model, so no gas pressure is applied at the edge. This is constant at 1 atm.

  • Modeling in 2D plane deformations.

  • Hydraulic law: “LIQU_AD_GAZ_ATM”

  • 50 \(Q8\) items.

The simulation is carried out over one year.

4.2. Result of modeling B#

The results are qualitatively consistent with the expected results. This is a case of non-regression.

The pressure and saturation values are checked at node 14 (x=0.04; y=0).
