[Dune] AMG for Linear Elasticity

[Ansgar Burchardt]

Hi,

do any DUNE users have experience with using AMG for linear elasticity
problems?

I understand that unsmoothed aggregation AMG as implemented by dune-
istl should not work well as rigid body movements are not reproduced
well enough on the algebraic coarse grid levels.

Is there any experience which alternative (sequential) AMG
implementations are easy to use from an existing code using DUNE?  I'm
so far considering PETSc's AMG (or hypre which can be used via PETSc)
or Trilinos' ML.

Regards,
Ansgar
