围绕航空CFD软件前处理过程中的三维数据可视化需求开展研究。根据航空CFD软件前处理应用需求,基于Qt/VTK工具库对CFD前处理过程进行三维数据可视化设计,将三维数据显示模块与外部业务控制模块实时响应,直观地显示了计算域的网格信息,极大地方便了网格计算域的计算参数设置,屏蔽了繁琐的人机指令交互方式,实现了友好三维可视化人机交互。
Research around the 3D data visualization needs in pre-processing aviation CFD software. According to the requirements of aviation CFD software preprocessing application, the 3D data visualization design of CFD preprocessing is carried out based on Qt / VTK tool library, the 3D data display module and external business control module respond in real time, visualize the grid information of computing domain, Which greatly facilitates the setting of the calculation parameters of the grid computing domain, and shields the tedious man-machine instruction interaction mode and realizes the friendly three-dimensional visual man-machine interaction.
