Computational fluid dynamics(CFD)are used in many disciplines increasingly,but CFD post-processing has been one of the research hotspots and difficulties in the field. The flow field post-processing software with proprietary intellectual property right is developed with VB6.0 visualization language. Many functions for special application are custom-made,such as file data format,3D flow field display,graph zooming,arrow prettifying and profile display of container. The software can also fulfill selection of graphic region,and operation of copying,clearing,clear and manual painting brush. It was applied to numeri-cal simulation of 3D unsteady molten steel flow in the tundish,and realized various functions. The convenience was provided for analysis and processing of the calculated results of CFD flow.%计算流体动力学(CFD)越来越多地应用在许多学科领域,CFD后处理一直是该领域的热点和难点之一.应用VB 6.0可视化语言开发具有自主知识产权的流场后处理软件,针对特殊应用定制了文件数据格式、稳态和非稳态三维流场显示、图形缩放、箭头美化和容器轮廓显示等功能,同时也可以进行图形区域选择、拷贝、清除、橡皮擦、手工画笔等操作.最后软件应用于三维中间包钢水非稳态流动的数值模拟,较好地实现了软件的各种功能,为CFD流动的计算结果分析和处理提供方便.
