[Dune] A question of intersection

[Guo Hua]

Hi everyone:

In 3d parallized cube mesh, a face (intersection) is on the "processorboundary" and it is shared by two processors i and j.
then on processor i, if I run face.boundary() or face.neighbor(). Which one will return true?

I thought face.neighbor() should return true, however the neighbor entity is not owned be processor i,
but in processor j. i.e. face.outside() is on processor j. So I cannot do anything on this neighbor entity
on processor i?

If I understand correctly?

Cheers
Hua
