Mesh Generation Technique for Complex Aerodynamic Configurations

The grid generation of complex aerodynamic configurations is one of the key technique and the prerequisite of the numerical simulation of the complex flow field. In order to increase the accuracy of boundary treatment and whole filed computation,it is required that the mesh is orthogonal with the boundary,and particulary,it is better that the mesh is orthogoral in the whole field.In this paper,the conformal mapping and the solving partial differential equations combined with the algebraic method is utilized to generate the high quality two and three dimensional body fitted and boundary orthogonal mesh.
