电磁场时域积分方程方法(TDIE)在解决瞬态电磁问题和宽带电磁问题等方面显示出独特的优势,然而TDIE的数值计算方法——时间步进算法(MOT)的计算规模较大,严重阻碍了TDIE方法在求解电大目标瞬态电磁特性中的应用。文章在研究MOT并行算法的基础上,开发了基于.NET Remoting的电磁场分布式数值计算方案。数值结果表明,该分布式并行方案显著提高了TDIE的计算效率,为解决电大目标瞬态电磁散射问题提供了一条有效途径。
The TDIE method shows its unique advantages in solving transient electromagnetic problems and broadband electromagnetic problems. However, the numerical calculation method of TDIE - the time stepping algorithm (MOT) is computationally intensive and seriously hinders The Application of TDIE Method in Solving the Transient Electromagnetic Characteristics of TV University. Based on the study of MOT parallel algorithm, this paper develops a distributed numerical calculation scheme of electromagnetic field based on .NET Remoting. The numerical results show that the distributed parallel scheme can significantly improve the computational efficiency of TDIE and provide an effective way to solve the transient electromagnetic scattering problem of TV broadcasting.
