I wrote an email last week, but I still have no answer. Investigating further my code and the source code related to IS I noticed, that there is a flag pure_neumann which I guess should handle the singular Neumann problems giving the problem, but from my understanding of the code flow there is no situation it is set true. Is this flag a remainder from previous implementations or am I just looking at the wrong place? Furthermore I'm wondering about the size of the coarse problem. From my understanding it should include all interface DOF's? But the size I get is the number of subdomains... Last but not least I wanted to thank for the fast help you provide and to apologize for the questions, which may seem rather stupid but help me to find the right understanding. cheers, ando -- /"\ Grassl Andreas \ / ASCII Ribbon Campaign Uni Innsbruck Institut f.
