用ansys做了一个梁的瞬态动力分析，但不知为何在/post26中看到的节点位移时程曲线为0，请诸位大神帮帮忙
以下附上命令流:finish$/clear$/prep7k,1k,2,2l,1,2k,3,1,0.5et,1,189mp,ex,1,2e11mp,nuxy,1,0.3mp...
以下附上命令流:

!加载 其中i是时间，就是说这个荷载是随时间递减的
*do,i,0,0.00172,0.0001v=188304*(1-i/0.00172)*enddosfl,1,pres,v
solve
/post26nsol,2,4,u,y/grid,1plvar,2
这就是节点位移曲线，为什么是0，很奇怪，本人菜鸟，请高人指教，谢谢 展开
