Abstract

Abstract

A fast and efficient grid generation program has been developed for any two-dimensional configurations.In this scheme,the separate grids are generated in each zone with a high speed algorithm which makes the ratio of the coordinate increments satisfy a linear distribution along arc-length of a grid curve,and then they smoothly joined along the common boundaries to establish the grid for the complex configuration.The advantages of the scheme are as follows:First,the mesh lines have continuous slopes from one zone to another;Second,the degree of the mesh lines clustering can be well controlled by the distribution of the boundary points;And the third,the computational speed is ten and even several hundred times faster than the elliptic grid generation scheme which has been widely used nowadays.
