Default Gradient
Posts: n/a

I am calculating gradient of velocity on rectangular grid points using finite difference.(Geometry is simple and the points are uniformly spaced)

I found out that the results I obtained are quite different from the CFX results for the velocity gradient. especially significantly deviates at the boundary

What scheme does CFX use for gradient calculation? Results should not be not be the same but similar? I need help

Thanks, Selim
