Dear Jean-Paul. That's good, I will test the AMG with the stabilized approach and see what I can get. If the results are interesting (well they already are right now for ILU + GMRES) i'll open up an issue on the github for the dicussion on that more specialized topic. Thank you for everything Bruno
