Cosmos constraint in the shape of an unmodeled surface?
Cosmos constraint in the shape of an unmodeled surface?
(OP)
Hi,
Moderate 3-D and limited FEA experience here, but no SW time. I need to define a displacement constraint on a flat surface in the shape of a circle which is not on the part in question. There is a square x-section ring sitting on 3 circular posts to which it is bolted, and I need to constrain the ring (which is modeled) to the end-surfaces of the posts (which are not). Can I do that?
Thanks a lot

You must add one constraint for each restrained movement (Force X restrained translaction; Moment X restrained rotation).
But, to add the constraints, you must select enteties on which they'll apply (surfaces, edges,...). You must decide what better simulate the real assembly method. You mabe need to create addicional features to the part (like split curves) in order to have a good "real" model.

RE: Cosmos constraint in the shape of an unmodeled surface?
I need to create a new sketch on the surface that does exist in my model, and sketch those surfaces that contact it but do not exist in my model. Will I then be able to create a displacement constraint (Cosmos constraint, not an assembly constraint) distributed across the shape of that new sketch?
Thanks a lot for your help,
