How to find Center of Gravity after Optimization in Hyperwork?

Hello Friends,

 

As Optimization Inputs in my DESING Variables, the displacement for new shape Change, I want to calculate new Center of Gravity? How can I get in accordance to my Design variable new CG?

 

Make sure I am changing elements which is hollow section.

 

I have defined around 24 shapes and design variable.
