Before, I asked a very similar question, but then the Reason was -8, while now it is -9. The solution for -8 was to add a ground to my bidomain simulations. Now, I have a ground and I use the configure option "download-hypre" for the PETSc configuration, as was the answer for another similar question on this forum.
What is the problem here and how can I solve it?
Thank you a lot in advance!
