[Dune] How to obtain assign different material properties to meshes (tetrahedral) in Dune ?

[Oliver Sander]

Hi Benedikt!
No, currently the DUNE grid interface does not contain the concept of
domains the way UG did.  There has been discussion about including
this but so far nothing happened.  Personally, I think it is not
necessary.  An element's domain id is element data just like a
P0 FE function.  Just maintain a vector with the element ids in your
application and feed it to your problem assembler.

Hope this helps,
Oliver
