梁单元截面方向向量在一点重合的问题

考爱的小可拉

有大佬遇到过这个报错吗？
Error in defining or computing beam section normal in 4 elements. The elements have been identified in element set ErrElemBeamSecNormal.
The beam cross-section direction vectors coincide at a node in 4 elements. The elements have been identified in element set ErrElemBeamSecDirVect.

做一个框架的分析，报错的四个单元是相互平行的四根梁，不太懂，求解答。
