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 error or terminate. > For the AMG solver, are there some additional parameters to give? Do you use SuperLU or UMFPack or an iterative method after you preconditioned with AMG? Markus Blatt often advises to use the direct methods as the iterative ones are prone to breakdown. Might be worth a try… Bye Christoph -- AddressSanitizer is not expected to produce false positives. If you see one, look again; most likely it is a true positive!
