[Dune] Fwd: Re: YaspGrid, periodicity and boundary segment indices

[Martin Nolte]

Actually, test-alberta already works with a periodic DGF file (Note: You
need ALBERTA 3.0 for periodicity).

Hi Christian,

this is not true for the way Alberta / ALU implement periodicity. In
that case, only one change has to be made: On the boundary
outside.geometry after geometryInOutside need not be on the
intersection. For the kind of periodicity implemented in YaspGrid I
simply don't know.

Best,

Martin
