EigenValue Buckling Analysis displays wrong total deformation

  Hello, I'm trying to run an Eigenvalue buckling analysys in Ansys to obtain the first mode deformed shape for the tapered girder shown in the image. I'm getting a very close critical buckling value to the one reported in the bibliograpgy I'm studying but the total deformation seems to have a max value of 1mm, which makes no sense and i think is the reasons of some errors in a further non linear analysis. Do you know why I'm getting this result?

  Hi,
  
  Buckling mode shapes do not represent actual displacements but help you to visualize how a part or an assembly deforms when buckling.
  
  Please refer to this documentation for more details: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v195/wb_sim/ds_buckling_analysis_type.html?q=eigenvalue%20buckling
