修改inp文件后导入出错

ABAQUS错误提示：BAQUS error the ratio of deformation speed to wave speed exceeds 1.0
更改方法：加*SECTIONCONTROLS，NAME=SC，DISTORTIONCONTROL，LENGTHRATION=0.1或者YES也可以，加在MATERIAL前面；或 加*DIAGNOSTICS，DEFORMATION SPEED CHECK=OFF；或者加*DIAGNOSTICS，CUTOFFRATIO=RATIO（具体数值)
按照提示更改inp：
** Constraint: Constraint-1
*Rigid Body, ref node=_PickedSet18, elset=PART-1-1.tumo
** Constraint: Constraint-2
*Rigid Body, ref node=_PickedSet12, elset=aomo-1.aomo
*End Assembly
*Amplitude, name=Amp-1
0., 0., 1., 1.
*Diagnostics，deformation speed check=off
**
** MATERIALS

*Material, name=banliao
*Density
7.8e-09,
*Elastic
210000., 0.3
*Plastic
但更改后导入提示：Error in job 3-24-onestep-xiugai-1: Unknown keyword "diagnostics，deformationspeedcheck=off". The keyword may be misspelled, obsolete, or invalid.
