当前地下水流有限元系统关键问题的探讨

Research of Key Questions in Current Finite Element Analysis System in Groundwater

有限元分析法在地下水领域中得到了越来越广泛的应用。地下水流有限元分析系统如Feflow、Visual Groundwater变得越来越流行，然而它们在几何建模功能与有限元分析功能集成方式基本上沿袭传统模式，效率低下。此外有限元分析系统的网络功能微弱或甚至没有，难以适应未来的发展。文中这些问题进行了深入的探讨研究，提出地下水有限元分析系统应该采用基于特征的几何建模功能与有限元分析功能集成，并通过数据模型简化和协同安全访问控制达到有限元分析系统的网络化。

Finite element analysis is more widely applied in the field of groundwater. Finite element analysis softwares in groundwater flow, such as Feflow, Visual Groundwater, is hecoming increasingly popular. However, in integration methods of geometric modeling capabilities and finite element analysis, they are basically followed the traditional work mode and inefficient. In addition, network functions of finite element analysis softwares are weak or no, it is difficult to adapt to their future development. In this paper, the issues are discussed and studied in depth, finite element analysis system in groundwater should be used through the integration of feature-based geometric modeling and finite element analysis capabilities, and network function for finite element analysis system is achieved through data reduction and cooperative and security access control.
