Dear Dune,


I was woken up somewhat by the recent discussion on 'boundaryId'
and the fact that it is marked at 'deprecated'. Now, since we need the boundarId
quite much, what would be the 'clean Dune style' of using id's on boundary faces ?

Should we use

template<class GridImp, template< class > class IntersectionImp>
size_t Dune::Intersection< GridImp, IntersectionImp >::boundarySegmentIndex	(		 ) 	const [inline]

instead of:


template<class GridImp, template< class > class IntersectionImp>
int Dune::Intersection< GridImp, IntersectionImp >::boundaryId	(		 ) 	const [inline]



How does boundarySegmentIndex connect to boundary tags in the DGF file ?

Also, how would we use this in the parallel case ? This is most relevant for us.

Would it be wiser to not used DGF but read directly from gmsh ?


Thanks a lot for your enlightenment and have a great day!

Benedikt
