abaqus 存在distorted excessively，如何解决？ 20

在abaqus仿真中，楔块设置了边界载荷，当载荷是汉宁窗调制的正弦信号，在400kHz频率，模型就能正常允许，一旦改变频率就会报错。改变了网格，和时间步长也没有用，求大神解答
Error in job Job-28: The elements contained in element set ErrElemExcessDistortion-Step1 have distorted excessively.
Error in job Job-28: There are a total of 3 excessively distorted elements
Error in job Job-28: 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.

单元变形速率超过材料中弹性波的速率，导致单元扭曲。一般是材料参数不当或加载（载荷或强制位移）太大、速率过快导致
