Method is based on finite volumes with finite element shape functions being used for interpolation. The mesh defines the finite elements and the mesh dual defines the finite volumes. Once the...

Theory guide section 11.1.1.5 describes diffusion terms as being calculated from the element shape functions (the derivatives of the shape functions actually). Discretization of source terms is...

FYI... in CFX diffusion terms are based on the gradients that come from the element shape functions. There is some control over the shape functions (through expert parameters I think) but usually...

I didn't notice the words "grid independence" in the original post. Certainly just testing the advection scheme is not sufficient to claim grid independence.

Well, pressure is not a transported variable in the same way that velocity is. Pressure is a source in the momentum equations and is introduced into the continuity equation, but it isn't governed by...
