Hi all,
I have just extended the stokes-taylorhood example. The linear system is now solved
with a GMRes with no preconditioner. There is no preconditioner because there is no
preconditioner: all existing dune-istl preconditioners either choke on Matrix<BCRSMatrix>
or expect the diagonal elements to be nonzero. OTOH, currently the example uses a 4x4 grid.
That should work even without preconditioning...
Unfortunately, the program does not appear to converge against the correct solution.
Is there an existing Stokes/TH implementation in pdelab that I can use for comparison tests?
Cheers,
Oliver
