摘要
为了配合计算流体力学的迅速发展,为了适应航空航天高科技问题数值求解的迫切需要,我们研制了平面区域网格生成软件GRGES.这个软件包括七大模块,即输入、预处理、服务性程序、方法库、网格质量自检程序、输出、总控分析程序,程序全长约6200行Fortran语句.作为通用的网格生成软件,GRGES具有以下4点特色: 1.对选用的网格生成方法作了局部改进和适当的技术处理。
With preliminary applications of GRGES, this paper discusses evaluation metho-ds of grid quality and gives a check list of grid quality for nine examples. The listmay be used as a quantitative analysis of the features of grid quality. Characteristicsand adaptive range of grid generation methods chosen by GRGES are then analyzed.Finally, in order to obtain a computational grid with high quality according to theneeds of the users, it is emphasized that boundary data are to be suitably preparedand grid generation methods properly chosen.
