Hi Etienne,
as Christoph points out, the effect you see is that a problem occurs on one
process and other processes are waiting. I don't expect the linear solver to
cause the deadlock, since quite some care is taken there to avoid exactly that.
I recommend that you recompile with debug
Hi Etienne,
as I did never parallel runs with DuMuX myself, I can only guess.
My guess is, that your linear solver does not converge and you don't see
the error because some process is waiting for the result from a process
that terminated due to the failed convergence. So it will never
show the
Dear DuMuX users,
After Bernd's email, with my colleague Mustapha, we used the AMG solver
for our parallel computations.
As Mustapha told, it solved the problem but only partially since the
computations stopped without explanation as shown below
Newton iteration 2 done, maximum relative
