摘　　要：在苏锡常地区建立了一般意义上的重叠型多个不规则子域FEM并行模型,利用区域分解法在MPI环境中实现了并行求解算法,并使用C++完成了MPI环境中的混合编程设计。通过在常州、无锡两地实际并、串行的应用结果比较表明,并行模拟具有数据资料准备相对简单且精度高的特点,是解决大型化、复杂化地下水流问题的一种可行方案。The modeling of groundwaterflow in a confined-unconfined aquifer of multiple irregular superposed subdomains was documented in the study. Finite element method （FEM） parallel simulation technique （PST） was used for simulation. C ^＋＋ was conjointly used to edit the modeling codes program, which was run on a message passing interface （MPI） system- parallel virtual machine （PVM）. Through domain decomposition method under the MPI environment, the parallel model computing was then carried out. Finally, actual series of dynamic data of the exploited groundwater in Changzhou and Wuxi were utilized for the FEM parallel .simulation on a two co-jointly mounted Internet computers system. The studies demonstrate that data preparation for the parallel simulation was quite simple, and the results exhibite high data precision.
