[Dune] DUNE for DDM

[Oliver Sander]

Hi Dawid,
thanks for your interest in Dune.  It sounds like Dune together
with the extension module dune-multidomaingrid does precisely
what you need.  In particular, dune-multidomaingrid does allow
all the partition queries that you require, and you can also
connect to SuperLU for solving.

There is a short article on dune-multidomaingrid by Steffen Müthing
and Peter Bastian entitled "A Metagrid approach to Subdomain
Modeling".  Apparently it is not freely available on the web, but I am
sure one of the authors will send you a copy (they both read this
list).  Meanwhile you may want to check out the general Dune
documentation at http://www.dune-project.org/doc/index.html

Don't hesitate to ask further questions.

best,
Oliver
