In some cases, I get MUMPS error -9, i.e.: [2]PETSC ERROR: Error reported by MUMPS in numerical factorization phase: INFO(1)=-9, INFO(2)=98927
This is easily fixed by re-running the executable with -mat_mumps_icntl_14 on the commandline. However, I would like to update my code in order to do this automatically, i.e. detect the -9 error and re-run with the appropriate option. Is there a recommended way to do this? It seems to me that I could do this with a PETSc error handler (e.g. PetscPushErrorHandler) in order to call a function that sets the appropriate option and solves again, is that right? Are there any examples that illustrate this type of thing? Thanks, David <http://www.akselos.com>
