[Dune] AMG and block matrizes

[Christian Engwer]

Dear all,

does anybody have experience in setting up the amg with block
matrizes?

I tried to adopt to the amgtest.cc, but I keep getting errors like:

/home/christi/DuneAll/dune-istl/dune/istl/paamg/aggregates.hh:1235:
error: cannot convert 'const Dune::FieldMatrix<double, 21, 21>' to
'double' in assignment

It seems that there are certain places where blocksize = 1 is
assumed. As I don't think that that's the case, I guess that I did a
mistake and that I got some parameters wrong.

Cheers
  Christian
