A domain decomposition method for the three-dimensional shallow water equations

Abstract This paper deals with the implementation of a domain decomposition method for the three-dimensional shallow water equations. The domain decomposition method belongs to the class of generalized additive Schwarz methods. It is based on a local coupling mechanism that allows for a flexible formulation of subdomain interfaces. For a real-life application in the Netherlands numerical results are presented. The experiments are carried out on a HP workstation and on a CRAY C90.
