Linear thermal expansion analysis with RBE2 elements

Hello everyone,

I am carrying out a linear thermal expansion analysis on an exhaust system? The model consists of a few RBE2 elements connecting different components. I have assigned a CTE to the RBE2 elements similar to the surrounding steel elements using the alpha option? However, there are still a few locations that show high stresses near the RBE2s. Could you let me know if there is something else that needs to be considered?

    Hello,

    Please verify whether the initial temperature and/or temperature load have been correctly applied to the independent node of the RBE2s.
