Hi Bernd,
Thanks for your quick attention and explaination. While I am looking forward to
your analysis on my example, I will also be very appreciated to see your
validation results against analytical solutions, if they were documented.
Once I get your feedback and understand better, I plan to run a glass bead
packaging test and validate the solver against Kozeny-Carman equation.
Best,
-Shawn

Dear Shawn,
thank you for your mails. We have validated the Stokes model against some
analytical solutions, but this is quite some time ago. The discretization of
Stokes is not ideal in the sense that it takes equal order approximations of
pressure and velocity. This is stabilized, but nevertheless not as robust as it
should be.
We will have a look at your example as soon as possible and get back to you.
Kind regards
Bernd

Here are three validation tests I ran (see attached PDF). The standard test
show some small oscillation but the result is acceptable. The set-up is a bit
unusual as only one facet on the boundary received Dirichlet pressure BC.
