Dear OF's

i have a question concerning how OF calculates fvc::grad(gamma) in the cells connected to the centerline on a "cylindrical mesh". With the Gauss linear Scheme the gradient is calculated by summing up gamma_face*face_area, but how does OF cope with the gradient at this mentioned cells where one face per cell (the centerline) has no surface?

Thank you in advance,
