[dune-fem] Has the Schur complement approach been implemented in DUNE-FEM somewhere?

[Dedner, Andreas]

Hi Andrea.

I do not quite know what you are refering to? Do you mean an
Uzawa like algorithm for Stokes?
It would help if you gave more detail on the problem youi are solving and on the
method you would like to use.
Best
Andreas

Hi all,

I need to programme the Schur complement approach, with an appropriate preconditioner, to solve the linear systems I'm dealing with.
I was wondering if anybody has already implemented it, either in his own code or in the tutorials. Just not to reinvent the wheel, or to have some useful hints.

Cheers,

Andrea
