客车流场数值仿真的空间离散化系统开发

System Development of Space Discretization of Numerical Simulation to the Flow Field Surrounding Bus Bodies

客车车身周围三维拓扑空间的离散化是客车周围流场数值仿真的基础。研究利用 Visu-al C+ +在 Windows上开发 3D- Bus Mesh软件 ,以完成车身周围三维拓扑空间离散工作并生成有限元数值仿真需要的单元和节点信息数据文件。实践表明 ,软件具有高效、实用和方便的特点。

The discretization of the three dimension topological space around bus bodies is the base of numerical simulation to the flow field surrounding the bus.With visual C ++ programing language,3D BusMesh software has been developed in windows environment.The work about the three dimension topological space partition has been accomplished by using the software,with resulting in data files about elements and nodes information which will be used in finite element numerical simulation.
