The convergence criteria which was inserted earlier was used to view the effect of mesh refinement with a radius of 1.3278 inces4853 inches.

As one can see from the data above, over the course of the mesh refinement, the equivalent Von Mises Stress only changes by less than one percent. Thus, the solution has been verified with respect to mesh refinement. However, notice how the equivalent Von Mises Stress now lies above our constraint. While our optimization looked promising, we had not taken into account the slight change in results from a finer mesh. 

Optimization Methods

The optimization was carried using each of the four optimization methods offered in ANSYS workbench. Note that the default optimization method in ANSYS is Screening.
