abaqus中從導入inp的模型文件后出現錯誤 ：The volume of 6 elements is zero, small, or negative. Check coordinates or node numbering, or modify the mesh seed. In the case of a tetrahedron this error may indicate that all nodes are located very nearly in a plane. The elements have been identified in element set ErrElemVolSmallNegZero. 請問解決這個問題是不是需要將節點編號逆時針，如何將其方向改變?
