Figure 17-17: Prediction accuracy of Internal Energy and Rigid Wall Force (One Quadratic iteration)
Despite the relatively poor approximation a prediction of the optimum is made based on the approximation
response surface. The results are shown below. The fact that the optimal Radius is on the lower bound of
the subregion specified (Range = 50), suggests an optimal value below 50.
