[Dune] Internal boundary surfaces via the Dune grid approach ???

[Oswald Benedikt]

Dear Dune,

for the implementation of a boundary integral approach, applied to a finite element time domain electromagnetics algorithm
we need to evaluate certain field quantities on internal boundaries, i.e. on a boundary that is contained within the volume
mesh. As far as I know, this is not (yet?) supported in Dune ?

Since this class of algorithms may become quite important in the future, do you have any idea if this is planned ?

If not, how should we do this ? 

Just find out if a triangle is adjacent to 2 specific volume domains ? This may be viable but still be somewhat 
inefficient.


Thanks! Benedikt
