在solidworks画完齿轮，hypermesh画完网格，在abaqus插入预制裂纹，局部放大图见上图， 提交时 出现 xfem裂纹未能正确重生成，继续提交作业后，出现关于自由度的警告，不知道怎么回事?
警告内容如下
Whenever a translation (rotation) dof at a node is constrained by a kinematic coupling definition the translation (rotation) dofs for that node cannot be included in any other constraint including mpcs, rigid bodies, etc.
