Parallel Conservative Scheme for Solving the Shallow-Water Equations
MetadataShow full item record
To improve the simulation of nonlinear aspects of the flow over steep topography, a potential enstrophyand energy-conserving finite-difference scheme for the shallow-water equations was derived by Arakawa and Lamb. Here a parallel algorithm is developed for the solution of these equations, which is based on Arakawa and Lamb's scheme. It is shown that the efficiency of the scheme on an eight-node INTEL iPSC/2 hypercube is 81 %. Forty mesh points in the x direction and 19 in they direction were used in each subdomain.
