Is there a way to set up an equation goal to maximize stiffness to weight? I can't find a way to set up a global variable because that is defined in the part and does not have access to the simulation data. This is such a fundamental need for structural analysis that I find it hard to believe it isn't possible. I can't, however, find anything about how to do it in Help, or online searches.

If the stiffness is high, the displacement is low
Add a displacement and weight sensor to measure the values
