ABAQUS做模态分析时，出现
The volume of 82 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.求教怎么解决

检查网格质量！

The volume of 82 elements is zero, small, or negative. 将inp文件导出，修改这82个点的节点编号，逆时针编号。

谢谢
