surfaceInterpolationScheme::interpolate

If fvcfd.H is included, interpolate is available.

Equations used:

    for (register label fi=0; fi<P.size(); fi++)
    {
        sfi[fi] = lambda[fi]*(vfi[P[fi]] - vfi[N[fi]]) + vfi[N[fi]];
    }

Where:

• fi is face;
• P is owner;
• N is neighbour;
• vfi is to be interpolated (geometricfield.internalfield)
• lambda is meshweights (surfacescalarfield.internalfield)
• sfi is interpolated value

This is:

$\phi_{e,i}=\lambda_i \left ( \phi_{P,i} - \phi_{E,i} \right ) + \phi_{E,i}$
