Summary of results ====================== This test makes it possible to reproduce a classic case from literature and storage modeling: the injection of gas into a saturated medium. We do not have precise reference solutions to compare with, however the values and the shape of the results are consistent with those in the literature. So we are making it a non-regression test case. This test case makes it possible to test the various schemes available for modeling two-phase flows in 2D and 3D: * Classic finite elements *Decentralized finite volumes stop (modeling*_ HH2SUDA) These patterns all give very similar results.
