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

<install_directory>/tutorials/mv_hv_hg/animation. If you need help finding the installation directory, see Finding the

Installation Directory <install_ 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 <install_directory>/../. In order to locate the files needed, you will need to determine the path of the installation directory <install_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.

(6)

3. From the Tools menu (located at the top of graphics user interface), select Readers, Writers,

and Functions….

The Readers, Writers, and Functions dialog is displayed.

4. Select the Import Template tab, and review the path preceding the directory /templates/. This is the <install_directory> path.

Loading Model Files - HV-1000

In this tutorial, you will learn how to:

• Load model and result files

• Load various solver result formats

Tools

To access the Load Model panel:

• Click the Load Model panel button on the toolbar. Or

• Select Load Model from the Graphics menu.

The Load Model panel allows you to load the result files along with the model files. 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.

(8)
