做的的一个按正弦或余弦规律振动翼型的非定常流计算,设置包围翼型的那一块为可mesh motion的subdomain,计算出现了如下问题,请问斑竹及各位CFX高手,是哪儿设置出了问题
the expert parameter "ggi permit no intersection = t" 定义的是什么,怎么设置,请解答一下,万分感谢: xiaojuan_20@126.com

I';m thinking that you need to change the model

把你的文件也传上来吧，那样可能会更好一些，因为报错的时候，只是说在哪一个计算步出了错，有时候不同的原因会导致相同的报错，很难单单通过报错知道在哪里修改的。

谢谢
这个就是设置好可直接提交CFX-Solver求解的文件
不好意思,发了两个一样的文件

ICEM输出的网格文件-3
以前是把流场弄成整个一个区域,进行网格划分,那样翼型动的时候就很容易产生负体积,或者网格质量变得很差,没得出结果前就已无法继续进行计算
现听从高手建议把流场分成五块分别划分网格,然后定义包围翼型的网格 mesh motion .我琢磨着着就是比较好,可弄下来就是行不通,先是计算老是中止.在我设置了the expert parameter "ggi permit no intersection = t" 后计算进行完了,但就是那么一块网格动,它不压缩上下的网格
下面我把动的情况上传给大家看下

slurry ，请看下我传上的东西，问题出在哪儿？多谢
