| Abstract: | This paper analyzes the problem about gen erating blending surface,and points out the limitation of the methods generating blending surface with radius or PDE.In this paper,a method of generating blending surface based on physical energy minimization is presented.Especially,this method is able to solve the problem to generate blending surface between closed nonperiodic tube-like surface and other surface.The paper discusses the principle and solution method about generating blending surface based on physical energy minimization.The example generating blending surface between the aerofoil and the body of aerocraft and the example generating blending surface of three mouth tube are given. |
