Computing thermo-mechanical coupling problems, with a focus on analyzing thermal expansion induced contact stress

Hello teachers, I would like to use FEniCS for three-dimensional thermo-mechanical coupling analysis, with a specific emphasis on analyzing contact stress caused by thermal expansion. Could you please provide examples of using FEniCS for three-dimensional thermo-mechanical coupling analysis, or any helpful guidance? Thank you!

This project by @tianjuxue uses dolfinx, but might provide good ideas regardless.

Thank you very much! I will contact you again after I have studied this example.
