Hi,

I would like to map the boundaryField of the volScalarField Cvf to the areaScalarField Cs, to use afterwards fac:: operators on the boundary data.
I got a "template argument deduction/substitution failed" when I used:

Cs.primitiveFieldRef()=vsm.mapToSurface(Cvf.boundaryFieldRef());

It works with

Cs.primitiveFieldRef()=vsm.mapToSurface<scalar>(Cvf.boundaryFieldRef());

1. Is it possible to use mapToSurface without explicit declaration of the Type? It works for foam extend, but not for OF1712.
2. And would it make sense to overload the = operator for areaScalarField, so that one has not to use the primitiveFieldRef()? It looks not very OpenFoamish at the moment, but perhaps there is a good reason to not overload it.
3. Since no solver is using mapToSurface (the others are only using mapToVolume), is there a better method to transfer the boundaryField data from volField to areaField?
