Some improvement on technique of orthogonal curvilinear grid generation

Wen Wei

Abstract

This paper is concerned with a new method to determine the source terms(P and Q) of Poisson equations for grid generation. By using the source terms (P and Q) presented in this paper, a satisfactory grid can be obtained. The interior grid distribution is controlled by prior selection of the grid point distribution, along the boundaries of the region, and the orthogonality is satisfied. This grid generation technique will be widely used in the numerical solution of 2 D flow in rivers, lakes and shallow water regions.
