I guess the coarse level solver does not converge. Which means that
the program does not use a direct solver for this. My fault as I did
not activate this in the module.

I have fixed this. Please run git pull on the module to get the
changes and make sure that either SuperLU or UMFPack is on your system
and found.

You can check this by searching for the following entries in config.h
in the build directory:

#define HAVE_UMFPACK ENABLE_UMFPACK
#define HAVE_SUPERLU ENABLE_SUPERLU

One of them should suffice.

Cheers,

Markus
