1 SIMPLE METHOD FOR THE SOLUTION OF INCOMPRESSIBLE FLOWS ON NONSTAGGERED GRIDS
"... There are usually two kinds of grid arrangements used to solve the fluid flow problems: staggered grids and nonstaggered grids. For the nonstaggered grids, vector variables and scalar variables are stored at the same locations, while for the staggered grids, vector components and scalar variables a ..."

Analysis of Density Currents Using the NonStaggered Grid Fractional Step Method
"... A new approach for the solution of timedependent calculations of buoyancy driven currents is presented. The density distribution is not uniform throughout the flow field, however the incompressibility condition and Boussinesq approximation are assumed to be valid because the time variation of densi ..."

of density is not significant. This method employs the idea that density variation can be pursued by using markers distributed in the flow field. The analysis based on the finite difference technique with the nonstaggered grid fractional step method is used to solve the flow equations written in terms
RESOLUTION OF MAXWELL’S EQUATIONS IN A NON STAGGERED GRID MODEL
"... Abstract — In this paper a scheme to obtain an adaptive method in space for the resolution of Maxwell’s equations is presented. Using interpolating wavelets it is possible to obtain an adaptive grid allowing an economy of the computational resources. Using the non staggered grid model the stability ..."

"... Abstract. In this paper a finitedifference scheme for incompressible flow problems is treated. The scheme uses nonstaggered grid for velocity approximation. The method is particularly suitable for problems in which velocity vector is involved in additional quantities that enter the system of flow ..."

THE AMERICAN SOCIETY OF MECHANICAL ENGINEERS Computation of Incompressible Flow in Turbomachines Using the Primitive Variable Formulation
"... ABSTRACT The primitive variable approach is adapted here for the solution of incompressible flow in turbomachines using nonstaggered grids. In this approach, a pressure Poisson equation with Neumann boundary conditions is solved in lieu of the continuity equation. Solutions for the Poisson equation ..."

equation exist only if a compatibility condition is satisfied. This condition is not automatically satisfied on nonstaggered grids. Failure to satisfy the compatibility condition results in nonconvergent solutions. A consistent finite difference method which satisfies this condition using a nonstaggered
