Thank you for the answer! According to your statement > * Your bilinear form (lhs) only couples phi and phi, and psi and psi.

I think I found the error for that, and will fix it.
Concerning the solver: That has to be checked, too, I think GMRES will be more appropriate for that. Thanks! Am Montag, 21.
