Do I need a temperature-displacement step?

Do I need a temperature-displacement step?

Do I need a temperature-displacement step?

(OP)
Hello,

I'm trying to do an analysis with different temperatures within my model parts. The thing is that my punch consists of two parts with different temperatures. I tried a temperature-displacement step but got error-messages concerning the degrees of freedom and possible wrong element. Now I'm asking myself if a thermal analysis is really necessary or if it suffices to just aply thermal loads for each set?
I hope someone can help me...

Regards

RE: Do I need a temperature-displacement step?

Your description is not good enough to recommend something.

When you just want to apply a homogeneous temperature or temperature change for parts, then you don't need temperature DOFs. You can define it like a BC. So a static analysis and regular elements would be enough.
