Dear DuMuX users, with revision 13284, the AMG backend has been improved in two ways:
1. So far, PDELab 1.1 plus a patch has been needed for the backend. Now, it is based directly on dune-istl. Thus, if you are not using the multidomain applications of Dumux, you do not need (to patch) PDELab anymore. This also allows us to base the multidomain stuff on the recent release 2.0 of PDELab and dune-multidomain, without need for patching. See a dedicated email later today. 2. The convergence behavior is improved for parallel runs, at least for the cases tested so far. In particular, the same number of Newton iterations as for the sequential runs is observed. These improvements have been achieved by Markus Blatt, who will be happy to improve also your code: http://www.dr-blatt.de/. Thank you, Markus!
