提出了用于浅水流动和污染物运移大规模计算的大规模并行有限元策略。在非结构网格上进行的有限元离散基于浅水方程和控制污染物运移的平流-扩散方程的三步显式格式。这些基于非结构化网格的公式的并行实现是在陆军高性能计算研究中心连接机CM-5上进行的。数值算例表明，所提出的策略适用于各种浅水流动问题的大规模计算。
Massively parallel finite element strategies for large-scale computations of shallow water flows and contaminant transport are presented. The finite element discretizations, carried out on unstructured grids, are based on a three-step explicit formulation both for the shallow water equations and for the advection-diffusion equation governing the contaminant transport. Parallel implementations of these unstructured-grid-based formulations are carried out on the Army High Performance Computing Research Center Connection Machine CM-5. It is demonstrated with numerical examples that the strategies presented are applicable to large-scale computations of various shallow water flow problems.
