So I followed the suggestion to check the reason. But till now I can not find it out. So I try to use another way. I change the cross-section setting to a periodical&nbsp;boundary. It is work! I would like to know this interesting thing. 1. What the difference between the symmetry boundary and periodical boundary? 2. What kind of situation the symmetry boundary (or periodical boundary) have to be used? 3. How can I&nbsp; understand the symmetry and periodical boundary warning and the suggestion&nbsp;clear?Maybe you can give me some advice directly on my problem.
