ABAQUS分析时报错，提示：The volume of 8 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.

解决方案1：三维网格，且有Tie constraint→取消勾选tie constraint对话框里的：adjusted slave surface initial position。

解决方案2：Results里检查有问题的elements，找到对应的接触面并edit
