[Dune] Getting the list of neighbours for a given element of the grid

[Sacconi, Andrea]

Hi Andreas,

I'm currently implementing an algorithm that requires to know, for each element of the grid, its neighbours. Simply it'd be easier if I had a method that, given the current element, returns the list of neighbours; nevermind, I'll write down a routine that does so.

Cheers,
Andrea

The interesection iterator is the only way to access neighbors in DUNE. Why would you want to
have something else?

Hi everyone,

I've a question about the grid.
Suppose you're interested in finding all the neighbours for a given element of a conforming grid. Is there a method that, given an element, tells you directly which are its neighbours?
Or is it necessary to traverse the Intersections and get that information with a loop?

Thanks in advance!

Andrea
