Hello Dumux team,
We are, finally, in the post-processing phase, aiming at publishing soon ... but we observed a scaring issue concerning the verification of the BC at the inlet.
I'm using Dumux 2.12 with the 2p sequential model for a rectangular domain discretized with a cartesian structured grid with water inflow (q_w = 0.0001446759 kg / m^2 - s). At the inlet I also impose a Dirichlet condition on water saturation, s_w = 0.7856 (smax).
The observed issue is visible in the png file (boundary_condition_t=500_kern1.png):
the horizontal axis in the figure corresponds to the y axis of the simulation domain (m) and the vertical axis in figure reports the saturation levels, (s_w).
We see at t = 500 days from the start of the simulation which runs until 688 days.
So, as we can see, the Dirichlet BC at inlet, s_w = 0.7856 is not verified. At t = 0, it is ok, but at every later step not any more, getting a bigger and bigger discrepancy.
May you help me to shed some light on this, please?I enclose all necessary files to reproduce such behaviour, in case you have the possiblity to do it.
Kind regards, Lorenzo
