2.2. Results#

We draw the gas pressure and saturation profiles (zoom) at 10 and 20 years:

We can clearly observe a rise in gas pressure (\(\mathrm{0,7}\mathrm{Mpa}\) at 20 years) at the edge of packages as well as a very slight decrease in saturation in the geological barrier. The influence of diffusion can be clearly seen by observing the drop in gas pressure corresponding to the advance of the saturation front.

2.3. Tested values#

This test case has no reference value, so we make it a case of non-regression.

Tests are carried out on 4 values:
