[Dune] DUNE for mix FEM+FVM methods?

[Oliver Sander]

Hi Ali!
 From the description of your problem it seems that Dune is a
good solution for you.  The way Dune handles grids is extremely
flexible, and it is no problem at all to have two (or more) different ones
at the same time.  In fact I do that on a regular basis for various
kinds of domain decomposition and multiphysics problems.
We have various grids with excellent support for local grid
refinement.  We do not have an actual dedicated AMR grid yet,
but I think that can be added easily.
I suggest you have a look at our tutorials and online documentation.
Don't hesitate to ask on the list if you have further questions.

Best,
Oliver
