Dear All,

I am looping through all faceI in "owner" list:

const unallocLabelList& owner = mesh.owner();
const unallocLabelList& neighbour = mesh.neighbour();

gradU = fvc::grad(U);

forAll(owner, faceI)


and I would like to use the value of gradU[neighbour[faceI]] for some operations....

The question is: when a boundary face is taken as "faceI", I know there is no neighbour associated with it, so what would be the value returned by gradU[neighbour[faceI]]?
