[Dune] Dune dual mesh

[Christoph Grüninger]

Hello Bartosz,
as far as I know, there is no code available to generate a dual mesh.

There is some staggered grid code inside DuMuX, which does calculations
on a virtual dual mesh which is calculated on the fly within the local
operator. Not sure, whether this would be an idea regarding your problem.

Have you tried to find or write some preprocessing code which does the
calculation for you? It shouldn't be too hard to have some Python code
generating you a dual mesh.

Bye
Christoph
