摘　　要：将多尺度有限元法(MsFEM)与地理信息系统(GIS)进行有机集成,开发出基于组件式地理信息技术的地下水流多尺度数值模拟系统,实现求解区域的多重尺度离散、参数的可视化赋值、稳定/非稳定水流的多尺度数值模拟、粗尺度解的重构以及模拟结果的多方案显示等功能,使得MsFEM数值模型具有了图形表达能力,模拟结果更以矢量的形式存储,可供进一步决策分析。通过数值实例测试了系统性能,结果表明:以MsFEM为核心研发的集成系统为地下水流多尺度数值模拟提供了高效的可视化界面。A groundwater flow multiscale numerical simulation system is developed based on COM technology,which realizes multiscale discretization of the solution domain,visual assignments of the parameters,multiscale numerical simulation of steady/unsteady water flow,reconstruction of the coarse-scale solution and multi-method expression of the simulation results,by efficiently integrating MsFEM with GIS.It makes MsFEM numerical model has graphic expression and simulation results are stored in the form of vector for further graphic analysis and decision-making.The system performance is tested by numerical examples.The results show the integrating system with the core of MsFEM supplies effective visualized interface for the multiscale numerical simulation of groundwater flow.
