Local Fourier analysis of multigrid smoothers for the Stokes problem
Abstract: We present a local Fourier analysis of the Stokes equations for a finite difference discretization on staggered grids. We compare the commonly used Vanka smoother with a non‐overlapping variant of the Vanka smoother. While the latter is computationally cheaper, the convergence depends severely on the order in which the unknowns are updated. In contrast, the convergence of the overlapping method is not affected by the order.
