Differential Coordinate Transformation and Technique of Curvilinear Grid Generation

Sun Guang-cai

Abstract

The paper discusses the differential coordinate transform method.A set control function for the generation of orthogonal curvilinear grid has been proposed.Some curvilinear grid generation examples show that satisfactory grids can be generated for simple-connected regions and connected-regions with complex boundary by using the proposed control function.The curvilinear grid at boundaries is orthogonal and the interior grids can be adaptive to the variation of physical parameters of fluid.
