Hi Georg, I switched to UMFPack, it is better* and also a direct solver. Pardiso could be used, but you need a license. Have a look at at one of our Stokes examples how to use UMFPack.
* Faster, terminates more reliably with singular matrices and subjectively converges better. Bye Christoph -- People who are more than casually interested in computers should have at least some idea of what the underlying hardware is like. Otherwise the programs they write will be pretty weird. -- Donald Knuth
