Functional relation between velocity at cell center and flux
 
Hi,

I would like to know what is the functional relation between
the surfaceScalarField phi(flux) and the volVectorField U(velocity).

I think the face flux phi can be approximated by the following function "linearInterpolate(U) & mesh.Sf()" when I use the settings below:

laplacianSchemes{default Gauss linear corrected;}
interpolationSchemes{interpolate(HbyA) linear;}

Is my understanding right?
I'm not sure in the case of the correction is done to the laplacian.

Any comments or suggestions would be appreciated!

Regards,
Fumiya
