Hi,

there is a special list for dune-pdelab (see
http://www.dune-project.org/mailinglists.html), where you might get
your answers either sooner or more competent.

the ISTLBlockVectorContainer does not provide the full interface as
needed by BCRSMatrix. If you really need to call methods from
BCRSMatrix, you need to access the underlying container by calling
ISTLBlockVectorContainer::base()
