DOUBLE MESH METHOD FOR EFFICIENT FINITE DIFFERENCE CALCULATIONS

The double mesh method (DMM), which is a newly-developed numerical technique for the simulation of free surface problems by the boundary element method, is applied to obtaining finite difference solutions of the Navier-Stokes equation. The DMM uses two mesh systems that are dependent upon the characteristics of the equations or terms to be calculated. The viscous flow around a circular cylinder and the free surface flow around a Wigley model are calculated using the new technique, which is demonstrated to greatly improve the efficiency of the finite difference method.
