We develop a sixth order finite difference discretization strategy to solve the two dimensional Poisson equation, which is based on the fourth order compact discretization, multigrid method, Richardson extrapolation technique, and an operator based interpolation scheme. We use multigrid V-Cycle proc

A fourth-order compact difference scheme with unequal mesh sizes in different coordinate directions is employed to discretize a two-dimensional Poisson equation in a rectangular domain. Multigrid methods using a partial semicoarsening strategy and line Gauss-Seidel relaxation are designed to solve t
## Abstract A class of higher order compact (HOC) schemes has been developed with weighted time discretization for the twoโdimensional unsteady convectionโdiffusion equation with variable convection coefficients. The schemes are second or lower order accurate in time depending on the choice of the
