Both radii are to be optimized in this model. The component has
been manufactured through punching and should not have any deflections in its depth. Both
radii should remain identical; that is, the component should remain symmetrical. In free
optimization, the nodes on the left radius will shrink and the nodes on the right radius will
grow due to the nonsymmetrical stress distribution. The following figure illustrates the
initial model and relevant stresses: <p>
