Different results for beam3 and beam188
Different results for beam3 and beam188
(OP)
hello,
I tried to use ansys13 to study the effect of self weight on a Cantilever Beam, by following this tutorial: http:// www.mece.u alberta.ca /tutorials /ansys/IT/ Density/De nsity.html. 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 doubt that differences in the beam formulation would account for a difference in deflection of that magnitude. Since the ratio of the deflections is very close to 386/9810, I'd be looking at the units used for specifying the accelleration due to gravity.
