Comsol Mechanical Thermal Contact

In summary, the conversation is about a thermal mechanical contact problem that the person needs help with. They have provided a model but are encountering errors while computing it. The other person asks for more details and a problem statement with diagrams. The issue seems to be with the mechanical contact, specifically with the middle part. Even fixing it does not solve the problem and the person needs to make it unfixed.

hi,
can somebody pls help me with the model i have appended to this post?
it is a simple thermal mechanical contact problem but i don't know what is wrong about it and why there is some errors in it after computing.
thanks

Will you explain what do you have to do with the model?
Could you provide some diagram or something where you got the problem from?

As far as I can see you're trying to compute a multiphysics problem here. I can see you are trying to create a temperature difference and then there's also a continuous force load on one of the edges and there are three fixed constraints.

Would you explain further or post a problem statement with the corresponding diagrams.

Hi gezibash,
My main problem is about the mechanical contact. it is very problematic on COMSOL.
Here, the middle part has caused the problem. Before adding this part, the contact works (however with a low boundary force).

even fixing the middle part does not solve the problem. (however i need to make it unfixed).thanks
