[Dune] dynamic_cast cost

[Marco Cisternino]

Thank you Christoph,
unfortunately, I have no time to porting the code to the newer versions of dune.
In any case, I don't think it is a problem, I would say it is the way dune did the iterations on the intersections.
I don't know if the newer versions changed the way to do this. In 2.4 it is exactly the same thing (same line same file different location in dune folders)!
I don' t think it is a matter of version, but I didn't see the 2.5...
Anyone using alugrid in any version until 2.4.1 can experience the cost of this dynamic_cast by looping over the intersections. Am I wrong?
However, thank you for your reply.
Bests,

Hi Marco,
I cannot speak for others, but I doubt that ALUGrid 1.52 and
Dune 2.3 will receive the kind of love you would need.

It might be a good idea to create a minimal example that shows
the problem with the most current dune-alugrid. Then you can
open an issue in dune-alugrid's issue tracker.
There is even a slim chance, that the problem does no longer
exist in the current trunk. Then you can consider updating or
investigating the changes for a pack-port.

Bye
Christoph
