交互式网格生成技术研究

THE RESEARCH ON INTERACTIVE GRID GENERATION TECHNIQUE

探讨了分区网格生成的交互方法 ,包括交互输入、图形显示、网格质量检查、网格求解过程的随机可视控制等问题。在此基础上研制了一种具有交互性能的网格生成系统———BIGG。应用该系统生成的网格实例及流场解表明该交互技术是有效可行的 ,研制的软件系统提高了生成效率和网格质量。

An interactive method of block grid generation is studied, including the issues of interactive input, graphics view, grid quality check, visual random control of grid solving process, etc. An interactive generation system\|BIGG is developed by the above techniques. The numerical results of grid generation and flow solution indicate that the interactive technique presented is feasible and effective, the system\|BIGG improves the generation efficiency and grid quality.
