远程CFD仿真及在建筑设计中的应用

Remote CFD Simulation and Its Application in Architectural Design

数值仿真是评价建筑方案的有力手段 ,但一般工程人员不易使用。该文提出基于webservice的CFD计算服务 ,将服务请求和实现分开 ,降低系统的耦合性。围绕远程计算的特性 ,介绍了基于客户端、Web层、应用层和后台数据库的仿真平台系统架构 ,具体讨论了实现计算服务的统一接口及其描述。为减少用户对系统的干预 ,提出了计算伺服Agent以提高系统的智能性 ,并描述了其结构和工作原理。通过引入基于Java3D的交互式后处理界面以提高软件使用的友好性。最后开发了用以评价建筑群风环境的简单原型系统以检验方法的可行性。

Numerical simulation is a powerful approach to evaluate architectural scheme, but it is difficult for average technicans to use. This paper proposes CFD simulation platform based on web service. The separation of service definition and realization can greatly reduce system coupling degree as well as the difficulty for use. According to the requirements of remote CFD simulation, the paper explains the systematic structure of platform and gives a detailed description of unified interface of web service. To improve artificial intelligence of system and reduce clients' intervention, the paper presents agent-based computational assistance and explains the structure and work principle of the agent. By introducing Java3D-based interactive technology, the post processor has friend interface for use. Finally, the prototype of a simple system for evaluating building wind environment is presented to verify the approaches.
