摘　　要：通过求解椭圆型方程生成三维贴体坐标网格，采用分块技术生成多块结构网格体系。每个子区域转换成计算空间内的立体域，具有自身的曲线坐标系，从而所形成的整个网格系统不会过分扭曲和不规则，这将有利于对于复杂边界的真实飞行器绕流流场的求解。A general generation method is presented for the 3 D multiply blocked structure grid of a complex configuration flying body.The structure grids can be generated by decomposing the domain into any number of contiguous blocks,and each physics region can be considered to have been transformed to a rectangular computational region on which the curvilinear coordinates are the independent variables.Thus the generated grid is not too skew or unregular.Effect of control functions on grid generation is discussed.The given examples showed that the method may deal with arbitrary complex 3 D domains with the multi blocked structure technique.
