An accurate compact treatment of pressure for colocated variables
We propose a new scheme for the pressure treatment in computations of incompressible flow using a colocated grid arrangement. To avoid oscillations associated with the sparse non-compact stencil, we introduce a compact fourth-order equivalent of this stencil and study its advantages over the classical second-order averaging procedure.
