摘要 该文提出了一种快速单元级矢量有限元/自适应多层快速多极子并行算法,该算法可在单元级上完成有限元部分的所有计算过程而无须生成总体系数矩阵;通过将基函数和权函数分别用不同空间位置上的点源函数展开,使多层快速多极子部分的积分计算得到大大简化,转移过程可由快速傅里叶变换计算完成,与波形渐进预估技术结合实现了大型涂层体RCS的快速预估。数值结果说明了算法的有效性。 A parallel algorithm via Element Level Vector Finite Element Method（ELVFEM） and Adaptive Multilevel Fast Multipole Algorithm（AMLFMA） is introduced. In this algorithm the calculation of finite element method can be finished at elementary level and no need to form the global coefficient matrix. By expanding the basis functions and testing functions with Dirac functions on different position, the integration calculation of the multilevel fast multipole algorithm can be simplified and transformation procedure can be calculated by FFT. Combining this algorithm with Asymptotic Wave form Evaluation （AWE） technique, the RCS of electrically large coated scatters can be calculated fast. The numerical results show the effectiveness of the presented parallel algorithm.
