Geometry optimization

$

Hello everyone, I´m modeling a simple heat transfer - structural problem, wher I have a 2-D rectangle with a hole in the midle. First I apply a Temperature load that produces expansion in the structural analysis. Then I apply a pressure
in the top of the rectangle.

This combination gives me a stress result in my model. What I want to do is to find the optimum thickness in my rectangle (variable in x and y) that make that the stress in any point in the rectangle does not overcome some specific
value. Other restriction in the model is that the thicknes variable can´t pass under a minimum thickness d_min.

I want to know if i cant fin this optimal d variable with the optimization module and how to do it. I´m trying
with global objetive = abs(solid.sy-sigma_max), and in control global variable I have d as the control variable, and
d_min as my initial value.

Thank you for your help.
