[Dune] ALUGrid for tetrahedral simplices with periodic boundaries ?

[Benedikt Oswald]

Hi Robert, 

thanks for the quick answer.

This is very encouraging news indeed!

I will do as suggested and report on experiences with the feature
as soon as possible.

I do think that this is interesting for other users as well.

Have a good day! Benedikt
