[Dune] boundary id

[Oswald Benedikt]

Hi Dune Team, with respect to id's, may they be associated with
boundary faces or subdomains, from a practical point of view, it is very
useful to have these; now that the concept of subdomains is served
by the LGM flavour in the UG grid manager, it would also be very
useful to be able to access these in a Dune based application.

For example, we here have a number of grids in the LGM format,
used previously in pure UG applications, which we would like
to use, with full subdomain information, in a Dune based code
as well.

Therefore, to have this information would be highly welcome,
if feasible with reasonable effort, already in the upcoming
release 1.0.

Have a great day, Benedikt

Hi Andreas!
I would say that this is a definite post-1.0 feature.  In fact,
looking at the documentation of boundaryId I don't quite understand
what it is supposed to do precisely.  Hence I can't tell how
difficult it would be to build that feature in UGGrid.

Cheers,
Oliver

Hallo Oliver,

ich wollte nachfragen, wie schwierig es jetzt noch waere
die boundary ids in UG einzubauen. Du hattest irgentwann
makl gesagt, so ein Konzept gaebs in UG ohnehin...
Gruss Andreas
