Why does the solved problem not give the stress contour plots?

  When I want to plot the stress plots, it just gives the deformed geometry, all in red color. Why is that?

  Stress results in beam elements are typically on the cross section so we need to show that cross section in our window - to do that issue
  /ESHAPE,1
  
  Then do
  
  set,last,last
  plnsol,s,eqv ! VM stress
  
  See eshape command in help for more info.
  All the best

    Hi there, for my case I managed to get a contour ribbon. However, I couldn't show any contour on my beams. Could you please advise where can I set this up?

  Thanks a lot Erik, that solved the problem, but why does the problem in the following link not need such procedure on cross section for stress plot?
