  Maxwell3DDesign1 (Transient)
    [warning] Eddy effect settings may need revisiting due to the recent changes in the design.  The default value will be used for the object if the value is not specified.  (2:34 下午  十一月 21, 2010)
    [error] Wrong band mesh.  Suggested solutions: (1). Add the InnerRegion to wrap all moving objects. (2). Specify smaller normal deviation angle to InnerRegion (suggested angle is twice as much as band object surface). (3). If the band gap very is small, a small segment is needed for band object so that the smooth curvature can be built on band surface. (4). Band object has true surfaces, but no mesh operation or operation is too large. (2:35 下午  十一月 21, 2010)
    [error] Simulation completed with execution error on server: Local Machine. (2:35 下午  十一月 21, 2010)

错误里的第一条，  在InnerRegion设置时，因为电机的转子是圆形，在MAXWELL菜单中Creat Region设置为方形，如何设置圆形Region？
使用Draw Regular Ployhedron代替Creat Region是否正确？？

   麻烦各位姐妹、兄弟中的高手帮帮我！！1
