An Extrapolation Cascadic Multigrid Method Combined with a Fourth-Order Compact Scheme for 3D Poisson Equation
In this paper, we develop a new extrapolation cascadic multigrid (ECMG) method to solve the 3D Poisson equation using the compact finite difference (FD) method. First, a 19-point fourth-order compact difference scheme with unequal meshsizes in different coordinate directions is employed to discretize the 3D Poisson equation on rectangular domains. By combining the Richardson extrapolation and t...
متن کاملA Combined Fourth-order Compact Scheme with an Accelerated Multigrid Method for the Energy Equation in Spherical Polar Coordinates
A higher-order compact scheme is combined with an accelerated multigrid method to solve the energy equation in a spherical polar coordinate system. The steady forced convective heat transfer from a sphere which is under the influence of an external magnetic field is simulated. The convection terms in the energy equation are handled in a comprehensive way avoiding complications in the calculatio...
متن کاملA general meshsize fourth-order compact difference discretization scheme for 3D Poisson equation
A fourth-order compact difference scheme with unrestricted general meshsizes in different coordinate directions is derived to discretize three-dimensional Poisson equation on a regular cubic domain. The difference scheme derivation procedure makes use of the symbolic representation of the finite difference schemes and is easier to understand in such complex three-dimensional manipulations. We u...
متن کاملA fourth-order compact difference scheme on face centered cubic grids with multigrid method for solving 2D convection diffusion equation
We present a fourth-order compact finite difference scheme on the face centered cubic (FCC) grids for the numerical solution of the two-dimensional convection diffusion equation. The seven-point formula is defined on a regular hexagon, where the strategy of directional derivative is employed to make the derivation procedure straightforward, efficient, and concise. A corresponding multigrid meth...
متن کاملHigher Order Compact Scheme Combined with Multigrid Method for Momentum, Pressure Poisson and Energy Equations in Cylindrical Geometry
A higher-order compact scheme combined with the multigrid method is developed for solving Navier-Stokes equations along with pressure Poisson and energy equations in cylindrical polar coordinates. The convection terms in the momentum and energy equations are handled in an effective manner so as to get the fourth order accurate solutions for the flow past a circular cylinder. The superiority of ...
