abaqus 存在distorted excessively，如何解決？ 20

在abaqus仿真中，楔塊設置了邊界載荷，當載荷是漢寧窗調制的正弦信號，在400kHz頻率，模型就能正常允許，一旦改變頻率就會報錯。改變了網格，和時間步長也沒有用，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.

單元變形速率超過材料中彈性波的速率，導致單元扭曲。一般是材料參數不當或加載（載荷或強制位移）太大、速率過快導致
