Thickness Optimization of a semispherical shell

I am doing a thickness optimization problem with COMSOL 4.3b, I encounter some problems. My problem desciption is as follows:
A semispherical shell is fixed at the bottom circle edge, and a vertically-downwards fixed force is applied to the top point of the shell. I want to get the appropriate thickness distribution of the shell under the goal of minimizing the total displacement of the shell.
I think we can use the Shell modules and the Optimization modules in COMSOL 4.3b to solve the problem. And take thickness of the shell as the design varible, the constraints is the volume or the mass of initial shell remains unchanged. The objective function is minimize the total displacement of the shell( shell.disp ). But I do not know how to manipulate the parameters in COMSOL. I hope someone could tell me how to solve it using COMSOL.
I hoping anyone who knows the process could lend me a hand. Many thanks!
