A fully conservative zonal interface algorithm has been developed for ovethppert (Chimera) (nitss. In this new approach, overlapped zones are transformed into patched zones. Flux conservation is then enforced on the patch boundary in a local sense, thus guaranteeing global conservation. This algorithm also unifies the interface treatment for patched and overlapped grids. The zonal interface scheme has been successfully implemented into a cell-centered finite volume code. Test cases indicated that the newly developed interface scheme is indeed fully conservative, highly accurate, and possesses superior convergence properties when compared to the original Chimera scheme. 1995 Academic Press, inc.

A second-order-accurate finite difference discretization of the incompressible Navier-Stokes is presented that discretely conserves mass, momentum, and kinetic energy (in the inviscid limit) in space and time. The method is thus completely free of numerical dissipation and potentially well suited to
We present an extension of the genuinely multi-dimensional semi-discrete central scheme developed in [A. Kurganov, S. Noelle, G. Petrova, Semidiscrete central-upwind schemes for hyperbolic conservation laws and Hamilton-Jacobi equations, SIAM J. Sci. Comput. 23 (3) (2001) 707-740.] to arbitrary orth
Grid interface treatment is a crucial issue in solving unsteady, three-dimensional, incompressible Navier-Stokes equations by domain decomposition methods. Recently, a mass flux based interpolation (MFBI) interface algorithm was proposed for Chimera grids [Tang HS, Jones SC, Sotiropoulos F. An overs
