how to generate a series of grids

zdong_hn

呵呵，大家新年快乐，某CFD小鸟2014年的第一个帖子来了。

"NPARC Alliance Tutorial on CFD Verification and Validation" 中提到 :
"The easiest approach for generating the series of grids is to generate a grid with what one would consider fine grid spacing, perhaps reaching the upper limit of one's tolerance for generating a grid or waiting for the computation on that grid to converge. Then coarser grids can be obtained by removing every other grid line in each coordinate direction. This can be continued to create additional levels of coarser grids"

我的问题是:
比如我用ICEM 给划分了一个全部由六面体组成的3D网格来模拟绕流物外流场，那什么样的软件能够做到remove every other grid line in each coordinate direction？
谢谢大家推荐。

1,手工重新布点
2，自己写个小程序

当绕流物很外形很复杂时，这个隔一层一掉一层网格点，写程序实现是不是有点不现实？
难道只有手工重新布点啦。。。。。。
