我在用abaqus進行螺旋軸的顯式動力學分析，進行網格劃分時，整個模型分割成了螺旋和軸兩部分

放著兩部分分別進行了疏密不同的網格劃分，但是網格質量檢查室，發現了上圖（左）的現象，黃色的單元出現了警告。提交作業沒有錯誤，但是分析結果如上圖（右）所示，監控里面有警告如下：

The option *boundary,type=displacement has been used; check status file between steps for warnings on any jumps prescribed across the steps in displacement values of translational dof. For rotational dof make sure that there are no such jumps. All jumps in displacements across steps are ignored

Degree of freedom 4 is not active in this model and can not be restrained

370 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

There are 3 warning messages in the data (.dat) file.  Please check the data file for possible errors in the input file.

請問一下大神，我該如何解決這個問題
