abaqus中从导入inp的模型文件后出现错误 ：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. 请问解决这个问题是不是需要将节点编号逆时针，如何将其方向改变?
