Preconditioning for the steady-state Navier–Stokes equations with low viscosity. (English) Zbl 0935.76057

The development of a preconditioner for the solution of steady-state Oseen equations in two dimensions provides the number of iterations almost independent of the viscosity. However, the preconditioner is very costly, and as no timings are reported here, a clear statement is yet not possible. Also, the author does not mention alternative of ILU.
