I'm new on that so I'll try to explain my self properly hehe.
I'm triying to do some finite element analysi withe the modul Analysis & Simulation of Catia V5-16.
The problem comes around when I try to define the loads on my figure. I'm working with an endlees worm and I have to apply the loads not in the whole perimeter but in a small surface, the one in contact with the gear. How can I define this surface? I have try to project a plane on the worm but it doesn't work properly.
I have the same problem when trying to analyze a spindle, as I do have to apply the loads only in just a pair of the threads and I donīt know how to do that. I have read something about the extract modul but nothing especific neither good explained.
