Hi, I'm working on a relativily simple model of an Acetal Bushing that is pressed into an aluminum bore.
Are you running a 2D or 3D model?
I add a global thermal stress of 0 and constrain the ID surface of the bushing in all directions.
I can't say definitely without looking at your model, but I'm fairly sure that this constraint isn't realistic; the net result of it will be higher stresses. When you press the bushing into the bore, the ID of the bushing will shrink; your constraint prevents this.
Also, what do you mean by the global thermal stress of 0? Did you add a global thermal load? If so, why?
When I run a quick check I recieve a failed convergance error and I can't figure out why
Yes, because Quick Check does not do a convergence study. A Quick Check runs solves the model with p-order of 3 for all elements and then reports the values; since the p-order hasn't been escalated and the model resolved, there is no way to check convergence.
