Start by double clicking on Response Surface in the Project Schematic window. Once the Response Surface window opens click Update. After, the update has completed click on Response to see a plot of the volume as a function of hole radius.

 

Note: Don't worry if you are using a newer version of ANSYS and your results don't quite match the results shown here. In version 2019 R2, we found the maximum von Mises stress to vary between 32.39 ksi and 34.22 ksi for the given input parameters, instead of between 31.91 ksi and 34.16 ksi as shown here.

Volume

The first plot which should appear shows the volume of the quarter plate as a function of the hole radius, and is shown below.

The relation between radius and volume is quite trivial to compute. It will simply be the area of the surface multiplied by the thickness of the surface. With this in mind, V=t*(h*w-(1/4)*pi*r^2) where V=volume, t=thickness, h=height, w=width and r=radius.
