Hi, I'm working on a relativily simple model of an Acetal Bushing that is pressed into an aluminum bore. I'd like to determine the stress distribution on the contacting surface of the Acetal bushing after installation. I have created a simplified model of a .751" OD (.500 ID) bushing and an aluminum bore of .750. I define the contact surfaces as the OD of the Acetal and the ID of the Aluminum. I add a global thermal stress of 0 and constrain the ID surface of the bushing in all directions. When I run a quick check I recieve a failed convergance error and I can't figure out why. Any suggestions? I can probably get a screenshot of the setup tomorow if that helps...
Thanks,
