CV flux correction in SIMPLE

Sophie

HI All, In my code I need to construct a residual analytical function (Navier-Stokes) using FVM. The solution of any code based on SIMPLE algorithm on a colocated grid I introduce in my code does not satisfy the mass conservation, since I don't know how to correct the velocity on the face explicitely from a given (U,V,P) on the cell center. I tried the Rhie and Chow interpolation but it seems implicit.

In the staggered arrangement case, I don't have this pb since the velocities given are on the cell face.

Any idea?

Thanks a lot
