[Dune] FW: H5Fed into Dune as a grid manager, comments, ideas ???

[Oswald Benedikt]

Hi Christian, yes, local refinement with hanging nodes is  is already
available in the current H5Fed (which has no connection to Dune yet)
including tags and adjacencies; i.e. we can attach and read / write
data to any top. entity on any level; data may be scalar, vector and
matrices of type double, complex, integer.

Maybe we should use derive from the grid factory class
and add additional member functions ?

Well, the grid factory is only for coarse grid creation. I suggest to
support this interface, but you will need more. Do you intend to
implement a full grid manager with local refinement etc? In this case
you will also want to add read/write methods for your "internal" data
format.
