[Dune] processor boundaries on nonoverlapping grids

[Alexander Schlaich]

Dear Dune,

I need to detect the elements in my parallel UG grid which are on
processor boundaries.

I read the documentation for the intersection():
http://www.dune-project.org/doc/doxygen/html/classDune_1_1Intersection.html

As I understand this method does not offer me the possibility of
detecting processor boundaries for ghost elements as I can't decide
wether they are ghosts or neighbours.

Is there a way of detecting the ghost elements? Am I reading the
documentation in a wrong way?


Thanks a lot for your anwers,

Alex
