Tehnique for Two and Three-Dimensional Body-Fitted Grid Generation

Lin Chaoqiang(Northwestern Polytechnical University)  
The using of Laplace equations to generate two-and three-dimensional body-fitted grid system is given in the present paper,and the AF1 schemc is uscd to improve the convcrgence of itcration process.The corresponding Dirichlet boundary vaIue problems for two-and three-dimensional cases are investigated first.For the two-dimensional case,the typicaI O-,C-, and H- grid systems are discussed in soME details,with special attention paid to the grid on the cuts to insure the smooth-ness of the grid lines there.For three-dimensional case,the body-fitted grid system for a simplified space shuttle geometry is shown. Special treatment for those grid points on symmetric plane,on the axis,and on the bottom surface is discussed,so that the grid system possesses good quality on the boundary,as well as inside the field.
