SIAM Journal on Numerical Analysis, Vol. 33, No. 1 (Feb., 1996), pp. 399-416 (18 pages) We use Fourier analysis to examine multigrid convergence for a variety of discretizations of the two-dimensional ...
A full multigrid method and fourth-order compact difference scheme is designed to solve the 3D Helmholtz equation on unequal mesh size. Three dimensional restriction and prolongation operators of the ...
Cascadic multigrid methods represent a class of iterative solvers that have been developed to efficiently tackle the large-scale linear systems arising from the discretisation of partial differential ...
