Design Optimization 387

For the Objective, the default setup is to minimize the Compliance, which is
equivalent to maximize the structural stiffness. Accept this default setup.

For the Response Constraint, we can choose exactly what response we want to
add constraints, e.g., constraining on the mass, volume, von-Mises stress, dis-
placement or reaction forces. Here we want to achieve 75% weight reduction.
Therefore, we select Mass for Response, and set Percent to Retain as 25%.
