HyperWorks Desktop Environment

HyperWorks Desktop is a set of applications that allows for the visualization and analysis of results and data obtained from a solver. Results obtained from often used solvers like OPTISTRUCT, NASTRAN, ABAQUS, LS-DYNA, ANSYS etc… can be viewed, analyzed and plotted using these applications. In addition, you can also set up a multi-body analysis. The open architecture of HyperWorks Desktop coupled with its automation capabilities allow for an easy, quick and complete understanding of your analysis results. This chapter helps you in getting a better understanding of the interface, the tools and the terminologies that you come across while working with HyperWorks Desktop.

HyperWorks Desktop belongs to the HyperWorks software suite and consists of the following applications:

• MotionView
• HyperView
• HyperGraph
• HyperGraph 3D
• TextView
• MediaView
• FE Model

This chapter contains:

• Elements of the Graphics Interface Features
• Page and Window Controls
• HyperWorks Desktop File

Section 1: Loading Model Files

The open architecture of HyperView allows for loading and viewing result files obtained from several sources. Based on the solver type the files are obtained from and the results you would like to visualize and analyze, there are different ways to load the input deck and their corresponding results into HyperView. This chapter guides you through the various ways you can load your files and the various tools available for viewing the model according to your interest.

In this section, 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.

Animation Types

A brief description of each animation type is given below:

Transient Displays the model in its time step positions as calculated by the analysis code.

Linear (^) Creates and displays an animation sequence starting with the original position of the model and ending with the fully deformed position. An appropriate number of frames are linearly interpolated between the first and last positions.

Modal Creates and displays an animation sequence starting and ending with the model’s original position. The deforming frames are calculated based on a sinusoidal function.

Step 2: Animate from time 0.00 to 0.04.

17. Click the Animation Controls button,.
18. Click the Current time first arrow , to display the page at time 0.
19. Move the Animate end slider to the time 0..
