Re: The model does not contain sufficient restrictions

Denis,

The example I have attached is based on your original image you posted of your problem.

I made a lot of assumptions like I'm assuming you have a clearance hole between the legs of the rectangular part and the pin and that you are only constraining it at the ends of the pin, material?

I added surface regions for each contact and for each displacement constraint.

I have added 3 springs to stabilize the parts so the analysis can begin from a know starting point.

I have added contact to each of the fingers

I constrained the ends of the pin

and applied the material to each part.

If the pin has a press fit you will need to use a deferent model setup than what I have provided,

 

See if the attached files help,

Don Anderson
