摘　　要：研究了CGNS数据标准及其数据结构,采用Tecplot的可视化功能及其宏命令作为开发工具进行后处理接口的开发。接口实现了读入CGNS文件后区分物面、对称面,多窗口显示,绘制云图或等值线,计算给定参考值下的压力系数并将计算结果插入Tecplot数据中等功能。结果表明,后处理接口统一了数据的输出格式,实现了自动绘制,方便了计算结果的后处理和分析。In this paper, a calculational software integration system adopting CGNS data standard is studied, and post - processing interface to this integrated software is developed. The implementation of the post- processing interface is done with a graphical toolkit Tecplot as well as its macro functions. And some post- processing processes such as wall and/or symmetry distinguish, multi- frames visualization, contour drawing, pressure coefficient computation, etc. can be achieved using this interface. The results show that, data output formats can be unified by this post- processing interface, also post - processing and analyzing of the computational results can be achieved with great convenience.
