[Dune-devel] Setting UMFPack parameters

[Oliver Sander]

Hi Markus, hi Dominic, hi all,
I have been playing around with the ISTL-UMFPack wrapper recently.  As it turns out,
I can solve my problems six times faster without noticeable loss of accuracy by
switching off iterative refinement.  However there is no way to do that through the
interface.  More technically, I need to set values in the UMF_Control array.
Before I start hacking, do you have any specific ideas how an official way to modify
UMF_Control from the outside should look like?
Cheers,
Oliver
