    Hi @tiago3008

    Could you please share details of optimization?

     

    It would be better if you can share the model file with us.

     

    Please use the file transfer link in my signature to share the model file

    When you say you don't know how to do that, I think it's better you begin some simple tutorials in your installation.

    Hi @tiago3008

     

    From your model, I learned that design constraint is volume and the upper bound is given for compliance as 0.03 which mean solver will remove almost all the material. 

     

    How did you arrive at a compliance value of 0.03?
