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

[Erik Kostson]

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?
