Optimization Using Inspire & Optistruct

I used solidThinking Inspire and optistruct to perform optimization. The mass of the bracket was reduced from 0.894 kg to 0.394 kg which leads to 55.9% reduction of mass. The factor of safety for the three load cases were 1.2,1.3 and 1.3 respectively. I found Inspire very effective and easy tool to use for optimization.
