Hi All,
I am doing a dynamic simulation in which I have a shaft attached to a gear by some screws, so when the gear rotates the shaft rotates as well. Then when I carry out a dynamic simulation, both the gear and shaft appear as a welded group, but I want to export only the shaft for a FEA. Currently this is not possible because this cannot be done with welded parts (that is the error message I get).
How do I take out the shaft out of the welded group so I can do the FEA?

But the dimensions are accurate and I set the material so wood, so again the resulting mass should be approximately correct.
Actually, you set the Appearance to wood, not the material. The material is set to Default (which is same mass as water).

You should get interference since the threads are cosmetic rather than cut. The cut threads will engage providing the clamping force.

Hi JDMather,
I've been trying to improve my dynamic simulation model because there were some redundancies and some times the automatic constraint generator created constraints that made no sense. By doing this I came along this two different Dyn.Sim. set-up however I'm not sure which one would be correct.
This one has all the shaft components, fasteners, and other parts, as mobile parts. (From my experience so far it's easier to do FEA on mobile parts):
But then on this one, the other set of fasteners is mobile and the big gear, among other parts:
So my questions is how should it look to know that it was done correctly? or are there different ways to set this up? So that I can stick to one set-up and focus on getting that one right.
At the moment I think the first one looks more correct than the second one.
Thanks
