@李东岳 好的，谢谢李老师

@李东岳
那么如果我在icem里面画的网格，interface的两个面大小不相等，要导入到openFoam里面，有什么解决办法吗？

@李东岳
感谢老师回复
顺便问一下，cyclicAMI两个面，其面积是可以不等的吗，我在纠结是不是这里有问题导致的出错。例如是下图两个面。

@李东岳
大佬救命，搞不懂嘎

各位老师和同学，本人是打算用icoFoam运算一个从Icem里面转化来的网格，在使用icoFoam试运行的时候，出现了如下错误，第一步就出错了。请问是什么问题呢？Icem里面的网格包含Interface,在openFoam里面设置了cyclicAMI代替，我猜测是不是这一步出了问题，因为interface相邻面面积不一致，我看cyclicAMI介绍好像有说相邻面大小要一样。
openFoam小白，还望各位赐教。

好的，我试试。感谢回复

这是我的createPatchDict文件。

请问各位老师和同学，在ICEM里面分块画的网格，所以包含interface，在openfoam里面打算用cyclicAMI面来设置。但用createPatch -overwrite命令的时候为什么出了下面的错误。
