Progress in Local Preconditioning of the Euler and Navier-Stokes Equations

Abstract

A multi-parameter family of optimal Euler preconditioners are explored. This uncovers the link between the various matrices derived by Van Leer et al. and Turkel, and also presents an attempt to derive more effective matrices. The preconditioning technique, which is based on a difference scheme rather than on partial differential equations, is extended from… (More)
