UNCONDITIONALLY STABLE EXPLICIT ALGORITHMS FOR NONLINEAR FLUID-DYNAMICS PROBLEMS

This paper describes novel explicit algorithms that are unconditionally stable. The algorithms are applied to some 1D convection and diffusion problems, including nonlinear problems. Algorithms such as these are of particular interest for massively parallel computers, where one is trying to minimize communications while at the same time maintain the stability properties normally associated with implicit schemes. It is shown how these stable algorithms can be applied in higher spatial dimensions and how they can be extended to problems defined on unstructured meshes. © 1993 by Academic Press, Inc.
