安澜模拟系统的构建与应用

Construction and application of Cross-scale All-dimensional Environment Simulation(CAES)system

我国水动力软件的系统性、集成性、通用性、界面以及开发工具、平台、数据库等方面与国外存在较大差距,严重制约了研究成果向应用转化和推广。鉴于此,构建了安澜模拟系统,该系统是一个跨尺度复合维度水沙生境模拟系统,集成了数据库、前处理、求解器和后处理等四大模块,实现了基于GIS平台的数据库管理、项目管理、网格/断面剖分和虚拟现实成果展示,集成了1/2/3维水沙、水质和水生态数学模块,尤其是在水沙数学模型中,不仅有传统水沙数学模型,还提供了两相浑水模型可供选择,强化了四大功能模块间工作流,使得模拟工作得以标准化、流程化、系统化。基于安澜模拟系统对长江-洞庭湖区域的水文地形数据、模型、项目方案进行规范化管理,对计算结果进行直观展示,计算值与实测数据符合较好。

Comparing with some of the world’s developed countries,the systematism,integration,versatili⁃ty,interface,development tools,platform,and database of the hydrodynamic software products in our coun⁃try is still in the initial stage of exploration,which seriously restricts the transformation of research results into applications.In view of this,Anlan simulation system is constructed,which is a cross-scale all-dimen⁃sional environment simulation system and integrates four modules including database,pre-processing,solver and post-processing.Based on GIS platform,the system realizes the management of data and projects,the generation of grid and mesh,and virtual reality visualization of results.The system integrates 1/2/3-dimen⁃sional hydrodynamic,sediment,water quality and water ecology numerical models.Especially in the wa⁃ter-sediment numerical model,both the traditional water-sediment numerical model and the two-phase mix⁃ture model are provided.The workflow among the four modules is so strengthened that the simulation work can be standardized,streamlined,and systemized.Based on the Anlan simulation system,the standardized management of hydrological topographic data,models,and project plans in the Yangtze River-Dongting Lake region is conducted,and the calculation results are visually displayed.The calculated values are in good agreement with the measured data.
