FEA: Force/deflection

[Cnoj]

OK I touched on this earlier: 'FEA: Generate force/deflection graph?' but I want to ask in more fundamental terms:

Can Inv 2010 FEA accept displacement as an input and give resultant force as an output? ie. I move one end of a  'spring' a known distance and need to know resultant force at the other end. 

Thanks,

Jon.

Yes.

Fix one end.

Then Fix constrain the other end and expand the dialog box and enter the displacement amount.
Then right Click on (the constraint I think - but don't have Inventor in front of me) in the browser to find the resultant force.

Attach your file here if you can't figure it out.

Success finally.

I was getting some very odd results until I discovered 'The reaction forces and moments can be inconsistent if the applied constraint shares a surface, edge, or vertex with another constraint.' in help.

Thanks.
