In this tutorial you will learn how to setup a study on simple functions defined using an Internal Math model. In this study you will set up a beverage can design of experiments to see how input variables effect the output responses. The beverage can has two input variables: Diameter and Height and two output responses: Material Cost and Volume.

1.Start HyperStudy.
2.To start a new study, click File > New from the menu bar, or click files_new_hst2 on the toolbar.
3.In the HyperStudy – Add dialog, enter a study name, select a location for the study, and click OK.
4.Go to the Define Models step.
5.Add an Internal Math model.
a.Click Add Model.
b.In the HyperStudy - Add dialog, select Internal Math and click OK.
6.Go to the Define Input Variables step.
7.Add two input variables.
a.Click Add Input Variable.
b.In the HyperStudy - Add dialog, add two input variables labeled: Diameter and Height.
c.Change both input variable's lower, initial, and upper bounds to the values indicated in the image below.

1.In the work area, set the Mode to Nominal Run.
2.Click Apply.
3.Go to the Evaluate step.
4.Click Evaluate Tasks. An approach/nom_1/ directory is created inside the study directory.
5.Go to the Define Output Responses step.

In this step you will create two output responses: Cost and Volume.

1.Click Add Output Response.
2.In the HyperStudy - Add dialog, create two output responses and label them Cost and Volume.
3.In the Expression column, enter the following:
a.For Cost, enter 2*(pi*dv_1^2/4)+dv_2*pi*dv_1.
b.For Volume, enter (pi*dv_1^2/4)*dv_2.
4.Click Evaluate to extract the output response values.

1.In the Explorer, right-click and select Add Approach from the context menu.
2.In the HyperStudy - Add dialog, select DOE and click OK.
3.Go to the Specifications step.
4.In the work area, set the Mode to Full Factorial.
5.Click Apply.
6.Go to the Evaluate step.
7.Click Evaluate Tasks.
