Jared Conway Jul 8, 2013 12:27 AM (in response to Stefano Tiburzi)On your question about Von mises, it is always positive. http://www.learnengineering.org/2012/12/whatisvonmisesstress.html?m=1
On your question about the force, do you mean comparing to physical, your beam analysis or some equation? Knowing what you're comparing it against will determine whether it is done correctly or not. But I'd say if you've done some mesh convergence and your displacement results match, your load application process is correct.

Stefano Tiburzi Jul 8, 2013 4:31 AM (in response to Jared Conway)Thanks Jared. The question about the force was in reference to DSV assumptions and related equations that I assumed by using beam elements. As I said I am a pretty new user to Simulation so I'd like to ask you how can I compare the results by a mesh convergence? Do you know if there's some tutorial i can learn it from?
Thanks again!

mesh convergence, check out this article by one of our sim engineers. http://www.hawkridgesys.com/blog/solidworkssimulationachievingconvergenceofresults/
this is also covered in the standard simulation class

Stefano Tiburzi Jul 8, 2013 12:07 PM (in response to Jared Conway)I beg your pardone, Jared. DSV = De Saint Venant, from De Saint Venant principle, the basic assumption from which beam equations are derived (lots of maths...).
Thanks for the link, I tried the hadaptive and seem to work very well!
Thank you very much.
