[dune-pdelab] ambiguosity in istlsolverbackend.hh

[Markus Blatt]

Hi,

I jsut wondered why it never happened to me until now. I think I know why now and there is no 
need for a working test case.

Can you confirm that and explain why your are using a PowergridFunctionSpace with the power one?
Why not a simple gridfunction for your case.


BTW: I really doubt that the parallel AMG backend works with UG.

Cheers,

Markus
