三维水动力数值模拟系统的开发

摘要

Three⁃dimensional hydrodynamic numerical simulation system (HydroInfo) with a variety of three⁃dimensional numerical model, pre⁃processing and processing subsystem was developed based on object⁃oriented programming, database storage and a new generation of graphics (WPF). It had several characteristics such as basic data input quickly, modeling process automatically, high efficiency and high precision numerical method, flow field with multiple performances and simple and practical assistant tool, etc. High⁃efficiency 3D graphics system had been set up, so that Eulerian and Lagrangian 3D flow field had been achieved. Real⁃time calculation results could be analyzed in the process of calculation avoiding useless computing, so the working efficiency was improved. Sever⁃al models of the HydroInfo system such as modeling, calculation and data processing had been verified according to the application of Douhudi at the Yangtze River.%利用面向对象的程序设计方法、数据库存储以及新一代的图形平台（WPF），以多种三维计算模型为基础，集成前处理、后处理子系统，开发实现了三维水动力数值模拟系统（HydroInfo）。该系统具有基础资料输入快速、建模过程自动化程度高、计算方法高效高精度、流场数据表现丰富以及辅助工具简单实用等特点。而且搭建了快速的三维图形系统，实现了欧拉以及拉格朗日两种方式呈现三维流场。在计算过程中能够分析实时计算结果，避免无效计算，提高了工作效率。以长江斗湖堤河段为例，对建模、计算及数据后处理各模块进行验证。
