Hi Suzon,
check if the linear system is set up correctly. Reduce the grid size to
as small as possible (like 1x6) and check if the matrix contains entries
everywhere you expect it. If non-zero entries are missing in the linear
system (matrix), you have an indictaion where to look for the error.
Bye
Christoph
