Hi David, Thanks very much! That solved the problem.

I am using the following command line options: ./example-opt -ksp_type preonly -pctype lu -pc_factor_mat_solver_package mumps So, if I understood everything correctly this should use a sparse LU decomposition to solve the system and not ILU? Thanks again, Kathrin It should be "-pc_type", not "-pctype".

You didn't say what command line options you are using, though so I'm just guessing that's the problem. -- John ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org<http://Slashdot.org>! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list [email protected]<mailto:[email protected]> https://lists.sourceforge.net/lists/listinfo/libmesh-users ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
