摘要:

将并行高阶矩量法在纯国产CPU平台中对电磁辐射与散射问题进行了仿真计算,并以散射问题为例,对算法的并行效率进行了测试.基于高阶多项式基函数的矩量法在保证计算精度的同时,可以大幅度降低传统RWG基函数矩量法产生的未知量.基于分块矩阵的高效并行策略进一步提高了矩量法的计算规模,并加速了仿真计算的过程.数值结果表明,采用的并行高阶矩量法程序,为在纯国产超级计算平台中解决复杂电磁仿真问题提供了一条有效的途径.

Abstract:

The parallel higher-order method of moments is firstly utilized to simulate electromagnetic radiation and scattering problems on a domestically-made supercomputing platform with its parallel efficiency tested. Higher-order polynomials over wires and quadrilateral plates, which can ensure accuracy, are used as basic functions over larger subdomain patches to reduce the number of unknowns. The parallel strategies based on block matrices can improve the computational scale and simulation speed. Numerical results show that the self-developed procedures provide an effective way to solve complex electromagnetic problems on the supercomputing platform.
