ABAQUS二维切削，在切了一部分之后工件中间破了一个洞是怎么回事啊？
报错是：
The ratio of deformation speed to wave speed exceeds 1.0000 in at least one element. This usually indicates an error with the model definition. Additional diagnostic information may be found in the message file.
Abaqus/Explicit Analysis exited with an error - Please see the status file for possible error messages if the file exists.
还请各位大佬如果有时间的话帮我解答一下，万分感谢
