In topology optimization when minimizing compliance for specified volume fraction, the maximum deflection of optimized structure is less than the maximum deflection of original structure?

based on this formula

For constant F when compliance is minimized U( deflection) should be minimized and vice versa. but in this formula volume fraction is not considered. 

I don't understand the concept of minimum compliance. The compliance of the optimized structure which is lighter than the original structure (since some material is removed from it) is even less than the original structure??!!

    Stiffness can increase as a result of topology optimization,

     

    Perhaps the discussions in the hyperworks optimization guide - practical aspects of structural optimization and the help documentation will help you with your study.
