Imperfection in nonlinear buckling

Hello

I have few questions

  1.  I want to do some nonlinear buckling analysis using imperfection. At start I made linear buckling and imported h3d file to the second model using ASSIGN card and IMPERF load collector, but it didnt work I guess because I don't see any buckling in results, only axial compression. HM and h3d files below. What should I do to make it work?
  2.  How to get safety factor in such analysis or critical load?
  3.  How to make xy plot with force? Sth like this in appendix

Thank you for your help
