[求助]大家帮忙看看这是个什么问题？怎么解决

如风似璧

在workbench中画网格的时候
错误提示：

Invalid periodicity in faces detected.
  CAD faces with double periodicity have been detected.
  These are most likely torii or connected components of
  toroidal surfaces. To mesh the problem you must cut these
  surfaces in two to avoid periodicity in at least one
  parametric direction. The problem faces are:

  (Body, Face) = (22, 26)

谢谢帮忙！
