Some Aspects of Grid Generation

摘要

New results concerning the development of a universal method for grid generation based onthe numerical solution of the inverted Beltrami and diffusion equations with respect to the monitor met-ric are obtained. In order to build monitor metrics, layer-type functions are used. Algorithms for gener-ating smoothly matched block grids are proposed. Examples of two- and three-dimensional grids for thetokamak edge region, for calculation of a passive impurity in the atmosphere, and for the numerical solu-tion of two-dimensional singularly perturbed problems are presented.
