Design of Experiments
This step samples specific points in the design space. It uses statistical techniques to minimize the number of sampling points since a separate FEA calculation in (and associated stiffness matrix inversion) is required for each sampling point. This is the most time-consuming step in the optimization process.

Next, double-click Design of Experiments. Again, we can see our input and output parameters but this time under the Design of Experiments step.
Highlight P1_-DS_R and change the Lower Bound to 1 inch and the Upper Bound to 2.5 inches.
Now, that the radius of the hole is properly constrained click on . ANSYS just picked what it thinks are the best sampling points according to an algorithm. Note that these sampling points are not necessarily linearly spaced. To get a numerical solution for each of these radii, click Update.
Click Yes on the the following windowIf you get the following error, click Yes.
Twiddle your thumbs a bit while ANSYS performs some time-consuming matrix inversions.
