hello,
I tried to use ansys13 to study the effect of self weight on a Cantilever Beam, by following this tutorial: http://www.mece.ualberta.ca/tutorials/ansys/I... . But I used beam188 as beam3 is no longer supported in ansys13, and I defined a rectangular section (B=50,h=10) instead of defining real constants (which is not possible for beam188). Instead of obtaining a 5.77 mm deflection (result found in the tutorial), I obtained a 0.22 mm deflection!! I tried to modify beam188 options, but I obtained the same result :(
Can you explain that? Is that due to the difference between beam3 and beam188? or there is a parameter that I should fix?
Thanks for your answers.

I just come to here and see there was no reply to princebouja. The diferent results come from the use of different gravity direction.
