DesignXplorer 14.0: Performing a Parametric What If Study
This tutorial gives step-by-step instructions for performing a parametric What If? study of a hitch re-ceiver. The workshop uses the Parameter Managerto investigate the behavior of stress, mass, and
deformation in the receiver as the geometry parameters are changed during vertical loading.
Note
What If? studies use functionality inherent to ANSYS Workbench. A DesignXplorer license
is not required to complete this workshop.
This tutorial covers the following sections:
1. Getting Started
2. Promoting Input and Output Parameters3.Working with Design Points in Workbench
4.Working with Parameters Charts in DesignXplorer
5.Viewing the Solution
1. Getting Started
Model Description
The model is composed of a multibody part (three bodies) created in DesignModeler. Constraints and
loads are shown below.
The dimensions labeled 1,2, and 3, shown below, will be promoted to input parameters.

3.Working with Design Points in Workbench
Adding and Updating Design Points
1. On the Project Schematic, double-click the Parameter Setbar. Alternatively, you can right-click the
Parameter Setbar and select Edit from the context menu.
2. In the Parameter workspace, add the three design points shown below to the Table of Design Points
3. Click the Update All Design Pointsbutton.
4. Click the Show Progressbutton in the Status Bar at the bottom right corner of the workspace. TheProgress Barshows the progress of the update.
When the update is complete, the Table of Design Pointsdisplays the results.

4.Working with Parameters Charts in DesignXplorer
Working with Charts
Note
The Chartsview may not be displayed by default. If you do not see the Chartsview at the
bottom right of the workspace, select View > Outline from the main menu.
First, well add a chart that illustrates the relationship between a selected output parameter and each
of the design points.

Note
An alternate method of viewing this chart is to select the parameter P6and then double-
click on the Parameters Chart P6 vs ?option in the Toolbox.
Next, well add a chart that illustrates the relationship between a selected output parameter and each
of the design points.
1. Select any cell in the IDcolumn of the Outline of All Parametersview.
2. In the Toolbox, double-click Parameters Parallel Chart (All) to add the chart.
3. Select the newly added Parameters Parallel Chart 0.

The Parameters Parallel Chart 0displays in the Chartview. Note that all the parameters are ar-
ranged along the bottom of the X-axis. The top and bottom values indicate the range relative to
each parameter. Each color-coded line on the plot represents a design point.
5.Viewing the Solution
Viewing the Solution
A solution is generated for the design point designated as Current in the Table of Design Points. If,
based on your design exploration, you decide that another design point is preferable, you can define
that design point as Current.
