abaqus切削仿真报错不收敛终止怎么办？

切削仿真的时候，前一步算的好好的，下一步就不行了，

报错：

The elements contained in element set ErrElemExcessDistortion-Step1 have distorted excessively.

There are a total of 4 excessively distorted elements

The elements contained in element set ErrElemExcessDistortion-Step1 have distorted excessively.

Abaqus/Explicit Analysis exited with an error - Please see the  status file for possible error messages if the file exists.

改了好多参数都只能算到13步，不知道根本原因在什么地方，求大神给指点一下，谢谢
