HyperView Tutorials Suggested Order
If you are a new user, it is recommended that you begin with HyperWorks Desktop Environment - HWD-0010 before working on any other tutorial.
File Location
All files referenced in the HyperView tutorials are located in the HyperWorks installation directory under /tutorials/mv_hv_hg/animation. If you need help finding the installation directory, see Finding the Installation Directory or contact your systems administrator.
Finding the Installation Directory Most tutorials use files that are located in the tutorials/ directory of the software installation. In the tutorials, file paths are referenced as /../. In order to locate the files needed, you will need to determine the path of the installation directory . This path is dependent on the installation that was performed at your site. To determine what this path is, follow these instructions: 1.
Bring up the application.
2.
Select HyperGraph from the Select application menu.

If the result file already contains the model definition, it is not a requirement that you load the model file along with the results. However, when only result files are loaded, the component definitions such as name and color are not preserved. The solver definition for component names along with the default color settings are loaded. You can also choose to load only a model or result file.
Load Model panel Activating the Overlay check box in the panel allows you to load multiple models and their results into a single window. You can then set the active model in the window from the View menu, by activating the Browser and selecting the HyperView tab, or by clicking on the file name in the status bar.

Performing Advanced Queries - HV-4010 In this tutorial, you will learn how to: •
Query results based on a contour value
•
Create groups of the queried entities
Tools To access the Advanced Query dialog: •
Click the Advanced button from the Query Panel menu.
The Advanced Query panel allows you to query components, elements, and nodes based on a value in the legend of an applied contour. This allows you to filter your model to display entities of interest for the contour that you have applied. You can also create groups of the data that you have queried, thereby preventing the need to query the same data multiple times.
Exercise: Using the Contour Panel This exercise uses the model file, truck.key and the corresponding d3plot file as the results file.
Step 1: Contour the model. 1.
Load the truck.key model file and the d3plot results file from the truck folder.
