where to search for a multiregion bc to transfer a vectorial quantity
 

dear FOAMER´s

I am searching for a good starting point to create an interface/bc similar to the temperatureBaffle for chtMultiRegion but instead of calculating a heat flux, i want the bc to behave like a zeroGradient for a vectorial quantity/volVectorField.
You could also think of it as a internal wall and the regions are glued together and share the same value for the vector at the bc but still are influenced from each others farfield values e.g. the other bc´s..

Hope i could express myself and somebody can shed a light. Even the tiniest would be great.

Thanks i advance.

As far as i understood regionCouple is only correct for scalars?!
But that´s a start...
