Abstract :
The development framework of parallel electromagnetic simulation software EMS-FMM based on multilevel fast multipole method (MLFMM) is present in this paper. EMS-FMM can solve large-scale scattering problem of 10 million scale with a complexity of O (Nlog N), so it´s efficient for electric large target. It´s implemented by C and Fortran with MPI communication on cluster DeepComp 7000. Implementation of MLFMM, interpolation algorithm for sphere functions, load balance and communication scheme for distributed octree structure are also discussed. The results demonstrate that surface current and radar cross section (RCS) of large complex target, such as plane and destroyer models, can be calculated by EMS-FMM.
