 ERROR # 312 FROM SUBROUTINE UKUERR
 For static load case        3 the compliance is large or negative.
 Buckling load case        6 cannot be solved.

  
 This error occurs in module 'asmbgkdrv'.

 

I am trying to solve a buckling analysis on a steering tie rod and I am getting this error.

I also checked my element connectivity and it doesn't have any free edges.

I would appreciate some help.

Below is the file.

    Hi

    you can search for ' compliance is large or negative ' on this forum, there are many discussions show that is due to 'not enough constraint'

    so check again constraint DOFs of your model. If model is still freely motion (like a mechanism), cannot perform buckling analysis
