带运动瞬态求解的问题讨论
这是V11自带的pdf描述的一个带运动瞬态磁场问题，本人是新手，昨天简单照做练习，一切均按部就班的做。前部分瞬态磁场计算是没有问题的。
加入band，进行运动求解时报错：
cannot compute tangential sign. possible causes are:
1)Incorrect geometry model;
2)Mesh is not correct.
Please try Model Resolution with suitable Model Resolution length.
添加了Model Resolution length后，报错：
The band surface is represented with too few segments. The maxmum angle pre segment is 15 degrees.
某次还出现了以下的错误信息：
Making single connected conduction region failed.Please check the motion setup.If a conducing region with a hole encloses the entire band, make this conductor be a solid conductor winding with zero voltage applied.It may help to cover the surfaces of conducting region which are facing band with insulating boundary.Also, there may be a problem with mesh, please check file 'bandmesh_msg' .
我的算例文件在上传的附件中，烦请各位大虾不吝赐教，万分感谢！
注：最后一幅图是从论坛上下载某位大虾公开的一个带运动瞬态求解的算例，能够成功计算。仔细分析了一下band的设置和网格，也没想出问题到底出在哪里？
