| 中文摘要 | 研究并实现了三维电与磁本构参数均为各向异性介质时的时域有限差分(ANI-FDTD)并行算法.根据电磁各向异性介质时域有限差分(ANI-FDTD)迭代式,电场和磁场某一节点场值的计算均涉及到其周围邻近28个场分量节点值.详细分析了该情况下各向异性介质时域有限差分(ANI-FDTD)并行算法中的数据通讯规律.通过采用相邻子域重叠半个网格的区域划分方式,传递分界面两边相关节点的场值,实现了局域网内各节点机的协同并行计算.数值计算结果表明了该算法和程序的正确性.; A three-dimensional finite-difference time-domain(FDTD) parallel algorithm for an anisotropic media(ANI-FDTD parallel algorithm) is presented,with dyadic permittivity and permeability on a distributed network by using the message passing module.According to the FDTD formulation of anisotropic medium,28 nodes are involved when the electric or magnetic field component at one node is calculated.The FDTD iterative computation at each sub-domain can be progressing successfully providing the field component values of interrelated nodes near the sub-domain interface communicate appropriately.The distribution of 28 related nodes is indicated and the way of message passing for field components between sub-domains in ANI-FDTD parallel computing are analyzed in details.The numerical results show the feasibility of presented scheme.; 国家自然科学基金(No.60371018) |
