Hi Nikolai,
I am sorry if I missed your previous posts and this question is
obsolete, but can you tell us what you mean by having corrected
darcyslaw.hh? I checked your repository but couldn't find a modified
version of the file, neither a respective branch in the dumux
repository. So I assume you have a locally modified version of the file
on your system?
There used to be a bug in the two-phase model with respect to the p1s0
formulation. That has been fixed about three weeks ago, have you pulled
dumux eversince?
Let us know if this helps!
Cheers,
Dennis

Dear DuMuX experts,
Please advise what can cause the following bizarre error: the code
compiled with debug options runs smoothly but the same code compiled
with release options crashes in the linear solver with the following
message:
Solve: M deltax^k = rNewton: Caught exception: "SolverAbort
[apply:/home/nikolai/dumux/dune-istl/dune/istl/solvers.hh:628]:
breakdown in BiCGSTAB - rho 0 <= EPSILON 1e-80 after 87.5 iterations"
This error pops up when working on a modified version of the
exercise-fractures test cases from dumux-course. Apart from modifying
the -problem.hh and -spatialparams.hh files, I have also corrected
darcyslaw.hh and switched the formulation to p1s0 (as described in my
previous post).
Compilation .opts files are attached.
May thanks,
Nikolai
