Input & Output Parameters

...

The Design Modeler can now be closed.

Objective Function: Minimize Volume (& Mass)

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. 

Additionally, if mass is also a desired parameter, check the box to the left of Mass.

Constraints: Maximum Von Mises Stress

{latex}$\le${latex}

32.5 ksi

Now, the maximum Von Mises Stress will be specified as an output parameter. In order to do so, (Expand) Solution > (Highlight) Equivalent Stress. In the "Details of "Equivalent Stress"" window, underneath Results, check the box to the left of Maximum. Once again a "P" should appear to the left of the box to illustrate to the user that the maximum Von Mises stress has been designated as an output parameter.

...

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.
