Hi, I have a problem that converges fine in sequential mode but diverges in MPI (other problems seem to converge fine for both modes). I am no expert in parallel solvers but, is this something I should expect? I'm using BiCGSTAB with BJACOBI ILU(3). Perhaps I'm overseeing some parameters that could improve my convergences?
