Hello,
Maybe this helps to understand what I’m talking about.
https://en.m.wikipedia.org/wiki/Minimal_working_example
In particular, “The important feature of a minimal working example is
that it is as small and as simple as possible, such that it is just
sufficient to demonstrate the problem, but without any additional
complexity or dependencies which will make resolution harder.”
Thank you for the link, quite instructive!
I do believe that I put all the minimal necessary information to
reproduce the behaviour.
Hi,
you send all the information to reproduce a rather complex simulation
setup. Not a minimal working example. Which features are necessary
really to reproduce the problem?
Do you really need custom spline material law implementations? Does the
same problem occur with the default Brooks-Corey Law? If no, maybe the
mistake is in the law. Are you sure the laws are identical to the ones
used in Comsol? Maybe there is some regularization which changes the
boundary behaviour. To eliminate that please use a Dumux law instead of
a custom law and see if the behaviour can be reproduced. The goal is to
single out every possible source of error to see only the effect of a
possible bug. I think your implementation is still too complicated to do
that.
If I understand correctly the erroneous behaviour should be visible
in an extremely simple 1d example as well. If not we can build from
there.
I'm not sure that in 1d would be visible.
Why not? What makes this a 2D effect? This is not clear from your
description. The solution plots look very one-dimensional.
Please understand that we are happy to help but we don’t have the
time and capacity to debug through large code examples with many
possible sources of errors.
Thank you, I appreciate.
Kind regards,
Lorenzo
