Millipede optimization

Hi,
my aim is to optimize the crosse section of my shell through millipede, in order to get a variable thickness according to the loads. So after the form-finding I used millipede and then Karama to evaluate the performance of the shell.
I want to make sure that in this way I can have a better structural performance because the thickness adjusts through the optimization process but I don’t know if the process is correct.
If anyone could tell me something about that, it would be very appreciated.

Thanks in advance,
