ANSYS进行瞬态动力学为什么POST1显示的应力图最大值和PSET26的结果不一样？？ 100

通过APDL命令流进行瞬态动力学仿真，但是查看结果时利用POST1显示的等效应力云图的最大值，查看该最大值节点号，然后通过POST26查看该节点应力变化，得到的结果不一样？而且差别很大。

若通过以下步骤得到的最大值节点编号也不是应力云图的节点编号？

ALLSEL

NSORT,S,EQV,0,0,ALL

*GET,MAX_SEQV,SORT,0,IMAX

通过POST26查看该节点应力值，确实比应力云图最大值节点处应力大。

本人的载荷文件时通过ADAMS刚柔耦合得到的lod文件，进行了适当编辑，编辑完成命令流如下：
