Abstract

Although unconditionally stable (US), the accuracy of ADI‐FDTD is not so high as that of conventional FDTD. In this paper, a high‐order US‐FDTD based on the weighted finite‐difference method is presented. A strict analysis of stability shows that it is unconditionally stable. And, more importantly, its numerical‐dispersion performance is superior to that of ADI‐FDTD. © 2005 Wiley Periodicals, Inc.

The lattice Boltzmann method is a microscopic-based approach for solving the fluid flow problems at the macroscopic scales. The presently popular method uses regularly spaced lattices and cannot handle curved boundaries with desirable flexibility. To circumvent such difficulties, a finite difference
