Dear Dumux community,With my colleagues, we are trying to perform an hydro-mechanical coupling model with Dumux.
We have first investigated the option to use the model "el2P" supplied in the test section of the multidomain coupling in version 3.4. In order to validate the coupling, we have been interesting in reproducing Mandel 's problem benchmark by taking into account of what has been carried out in Martin Beck 's publications and source code from https://git.iws.uni-stuttgart.de/dumux-pub/beck2019a .
Unfortunately, we are not capable to obtain good results on the pressure field where the Mandel-Cryer effect should be captured. As depicted on the images that we join to this mail, we are obtaining good results for horizontal and vertical displacements but not for the pressure which decreases directly at early times.
We have no idea of where comes from the issue, this is why we are kindly asking if someone has already been facing this situation.
Thank you for your help
