there are no metrics because the coordinate system is not transformed.
I used Green's theorem to convert the surface integrals to line integrals (since it's a 2d code)

hi Ramesh
I'm using a cell centered approach for solving potential flow over a body.
By cell centered I mean the potentials are calculated at cell centers, and my grid is the cell edges.
I need to...
