STUDY ON REVERSE-QUADTREE ADAPTIVE GRID TECHNIQUE

Abstract

The fast multipole method is universally adopted for solving the convection equation n the vortex method. In this paper, a reverse-quadtree adaptive grid technique s proposed in order to improve the quadtree adaptive grid technique in the ast multipole method. Taking flow past a cylinder as an example, the results indicate he reverse-quadtree scheme can save more calculation time than the uadtree scheme when the particle population is large enough.
