[Dune] [#80] Backup and Restore of Grids.

[Oswald Benedikt]

Hi Dune, somewhat more than a week ago I sent a mail to this list which was
exactly concerned with this kind of subject:

Our project H5Fed for storing (write/read) hierarchical meshes in a standardized way.

Unfortunately, nobody cared about this, it seems.

While I am convinced that a discussion about specific details of pointers etc are 
certainly very relevant for the long term evolution and stability of Dune,
from a more practical point of view I would sometimes wish that subjects 
concerned with applications needs, namely backup and restore,
or, I dare say, usage of boundary id's in ALUGrid, find more resonance
in this list (and are not downgraded to minor significance in the flyspray).

Thus, I repeat my plea: have a look at this project (h5.psi.ch)

Our idea is to connect H5Fed to Dune in a transparent way, but we need feedback
from the Developers.

Thanks and have a quiet night, Benedikt

Here's the UGGrid status: you can write grid hierarchies to disk, but you cannot read them.  This is the problem: in theory, UG has full backup/restore facilities.  However, in UG the domain boundaries are hard-wired in the C code.  Hence they are not included in the backup file.  To do a proper restore means to call the UG 'restore' method but get the domain information in there somehow from the side. I am convinced that this is feasible but it will need at least several days of work from someone who knows UG.
