The introduction into the continuity equation of additional terms to recover grid-scale ellipticity, for the Navier-Stokes equations discretised on a non-staggered mesh, results in an increase in the discretisation error. The introduced error is a combination of the additional truncation error and a
We describe some experiences using iterative solution methods of GMRES type to solve the discretized Navier-Stokes equations. The discretization combined with a pressure correction scheme leads to two different systems of equations: the momentum equations and the pressure equation. It appears that a
