An extrapolation full multigrid algorithm combined with fourth-order compact scheme for convection–diffusion equations
Abstract In this paper, we propose an extrapolation full multigrid (EXFMG) algorithm to solve the large linear system arising from a fourth-order compact difference discretization of two-dimensional (2D) convection diffusion equations. A bi-quartic Lagrange interpolation for the solution on previous...
