A block preconditioning technique for the streamfunction-vorticity formulation of the Navier-Stokes equations
Iterative methods of Krylov-subspace type can be very effective solvers for matrix systems resulting from partial differential equations if appropriate preconditioning is employed. We describe and test block preconditioners based on a Schur complement approximation which uses a multigrid method for...
