Error in mesh mapping on band, please check the potential problem in band setting. In the project with non-periodic translational motion or non-cylindrical rotational motion, the band can not have any curved surface.（翻译：标注栏上的网格映射出错，请检查标注栏设置中的潜在问题。在具有非周期平移运动或非圆柱旋转运动的工程中，带不能有任何曲面。）

解决措施：把圆环状的磁体内外都要分成100段，不能只分外圆；分成多段的好处是加快仿真
