I have a question about Free Body contribution and I am seeking a bit more clarity especially on Peripheral Elements & Free Body Elements.
Femap commands manual provides the following explanation:
• Peripheral Elements - When On, includes grid point force and moment contributions from the selected Output Set for the elements surrounding the Freebody Elements selected in Entities section.
• Freebody Elements - When On, includes grid point force and moment contributions from the selected Output Set for the elements selected in Entities section.
I did simple exercise, plate with tensile load to get a better understanding of exactly what each option does and it seemed obvious but for more complex case, I unable to get clarity. I am requesting more exprienced folks to help me understand the above.
Also, is there an option to restrict interface load only to selected/active group instead of the whole model?
When you go about selecting the elements for Freebody, if you select the elements in the particular group shouldn't that work out.
If I understand your problem correctly, the solution should be similar to what they do in this video: https://www.youtube.com/watch?v=EmcGOS94DC4
The group only has a few elements and when you select the elements in the group, you get the interface loads for that group.
I hope this helps.
