Input & Output Parameters
To set up the input and output parameters for a geometry created in Workbench, simply follow the steps below. To set up parameters for a geometry created in Solidworks, follow the instructions here
Design Variables: Hole Radius
The radius of the hole needs to be declared a design variable. In order to do so first, open the Design Modeler by double-clicking on 
from the Project Schematic window. Then expand XYPlane. Next, highlight Sketch1.
Now, check the box to the left of "R3", which will be in the "Dimensions: 3" part of the "Details View" table. When you check the box an uppercase "D" will appear within the box and you will be asked what to call the parameter. Call the parameter "DS_R".
The Design Modeler can now be closed.
Objective Function: Minimize Volume
This particular optimization problem has two output parameters: the volume of the quarter plate and the maximum Von Mises stress. In order to specify the volume output parameters, first (Open) Mechanical > (Expand) Geometry > (Highlight) Surface Body. In the "Details of "Surface Body"" table expand Properties then check the box to the left of Volume. A "P" should now be located within the box.

At this point the Mechanical window can be closed and you should save the project.
Let's review the input and output parameters that will be used in the optimization process. In the main Project Schematic window, double click on Parameter Set.
After doing so, we can see that DS_R is the input parameter, and the volume and max. value of the von Mises Stress are the output parameters. Now, return to the main window by selecting Return to Project.
