Thermal analysis problems

Hello everyone,
I’ve been trying to do a simple thermal analysis on a SNPB metal foam beam, and I don’t know what to do. I get the “Your analysis does not contain a sufficient set of constraints and would likely fail” error and I don’t know what to do.
Here is a link to the project.
Thank you!

Hi there!

Maybe this post helps you: I'm not able to start simulation - just make sure your system has enough constraints.

Cheers,

I saw the post, but i don’t know what constraints should i add.
Can you help me with that?

Hi @balberto,

Since this is a thermal mechanical problem you also need to constrain the model in 3D space. I fixed one of the circular faces and the model ran without any issue.

I hope this helps!
