creo interface questions

[hye]

I am new to Creo,

We try to run a simple FEA analysis for pipe systems using creo simulate.

IN ANSYS, All the interfaces/gaps  between the pipes can automatically detected---automatically assign contact, even if there is a big gap, still can "force" them to contact each other by using "pinball", as long as pinball size >= thye largest gap between pipes.

So I wonder if creo has same function to automatically fill those gaps automatically?

Thanks

Well, depends on what you mean by, "contact"; are we talking stiffness dependent behavior or just the ability to tie interfaces together? If it's the former, then yes (you can adjust the global definition under "Model Setup" by setting the default interface to "contact" and adjusting the separation distance). If it's the latter, then you'll need to ensure the surface/edges are coincident (or manually tie them with rigid links or weighted-links+springs).
