划分网格问题  急求助！

划分网格的时候出现：
Creating mesh...
Error 16504: The mesher encountered a problem.
Contact support with a description of what you were doing,
sending the model file (if possible), and the log file that was written to
CADFEKO.PROBLEM.LOG
Error 17580: The mesher aborted abnormally while meshing "Subtract2".
Mesh "Union2_1" with 2 segments, 404 triangles and 0 tetrahedra.
Created entry port "Union2_1.Wire70"
请问这是怎么回事呢

你把Subtract2和Union2_1分开划分网格看能解决不。

我试了把两个物体分开划分网格 还是出现这个错误 Union2_1是可以划分的 就是Subtract2不能划分 怎么办呢

新手！正处于学习过程中！

检查重复边或不连续边！如果还不行，在region处理一下封闭导体属性，设置为freespace并删除掉不可见面
