摘要
实际工程应用中的大规模数值模拟需要借助于并行计算。介绍了适合并行计算的非重叠区域分解法以及并行计算的实现。为了更精确地计算,建立了500kV高压输电线路及其周围房屋的三维模型,并把该模型划分为多个(2～6)分区通过机群来分别实行并行求解。各分区内形成的线性方程组通过Krylov迭代求解器求解。结果表明通过并行计算能够精确地计算线路附近的房屋周围各点电场强度,高压输电线路周围的房屋对外界电场有一定的屏蔽作用。
There exists large-scale numerical simulation in engineering application which will turn to parallel computing. Non-overlapping domain decomposition method and parallel implementation are described. A three dimensional model of high voltage transmission lines with the house nearby is built and decomposed into 2-6 sub-domains for more accurate calculation. The linear equations formed separately on each sub-domain are solved by Krylov iterative solver on a cluster of computer. At last, the results show that parallel computation can accurately calculate the electric field around the house nearby the high voltage transmission lines, and the house is helpful of shielding the electric field.
