Comsol Mechanical Thermal Contact

  1. Sep 27, 2014 #1
    can somebody pls help me with the model i have appended to this post?
    it is a simple thermal mechanical contact problem but i dont know what is wrong about it and why there is some errors in it after computing.

    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).
