HyperWorks 9.0 HyperView Introduction 5 Proprietary Information of Altair Engineering, Inc. Chapter 1: HyperWorks Desktop Environment HyperWorks Desktop Files Session File (MVW) Each time a HyperWorks Desktop application is launched, a new session is started. Saving a session creates a session (MVW) file, which allows you save the state of the current session. You can then close the session and restart it later without having to redo procedures. This file has an .mvw extension. An MVW file is a plain text file that contains commands that were performed in the operations of the corresponding session. Results and model file data are not stored in this file. Rather, soft links point to the data files used in the session, helping to keep the MVW file size small. If you move the data files to a different folder, the MVW file will not be able to locate them unless you edit the file path names in the MVW file. It is suggested that you save the MVW file to the same folder that contains the data files. You can edit the MVW file using a text editor. To save a session to a session file, select Save Session File from the File menu on the menu bar. To open the file select Open from the File menu. Application Files Each application in the HyperWorks Desktop can load and save its own set of files. Application specific files are accessed in the Applications’ user interfaces provided in the panel area of the HyperWorks Desktop. Preference Files The preference file is a script file that is read each time a HyperWorks Desktop application is started. It specifies default user settings such as the window type, printer, page layout, the autosave interval, and the order in which colors are assigned. A standard preference file for all HyperWorks Desktop applications exists in the installation directory and is read every time HyperView is started. On Windows, the file is named preferences.mvw, while on UNIX, it is named .preferences.mvw. Your own preference files can be created and registered under the File menu in the HyperWorks desktop. Depending on the setting, your own preferences files either overwrites or appends settings defined in the standard preference file. For example color settings overwrite the defaults but registering new readers appends to the supported file list. 6 HyperView Introduction HyperWorks 9.0 Proprietary Information of Altair Engineering, Inc Chapter 1: HyperWorks Desktop Environment Exercise: Learning to Use the HyperWorks Desktop Interface: In this exercise, you will: • Work with session files • Develop an understanding of the graphics interface • Use the page and window controls Step 1: Open the session file frontal_crash.mvw. 1.

In this chapter, you will learn how to: • Translate FEA animation data files to an Altair Hyper3D file • Learn how to create Hyper3D files • Translate animation data files using HyperMesh results translators Tools To open the HvTrans GUI • On Windows: From the Start menu, select Programs/Altair HyperWorks / Tools / HvTrans. • On UNIX: Run the script [HyperWorks install directory]/altair/scripts/hvtrans. HvTrans allows you to extract or translate results into an H3D file. A Hyper3D (H3D) file is a compact file containing model data, results data, or both, depending on the method used to create the file. The H3D file format is Altair proprietary. All H3D files, regardless of the method used to create them, can be loaded into HyperView. The HvTrans utility runs in GUI mode and in batch mode. In GUI mode, you can select the results you want to extract or translate, include the model information from the results file or corresponding input file. In batch mode, perform a translation without invoking the GUI so you can translate results on a file server if required.

Chapter 10: Using HvTrans To access the HyperMesh Results Translator • On Windows: Through HyperMesh, on the Analysis page select Solver. Through DOS, run the HyperMesh results translator scripts, which are located in the directory [HyperWorks install folder]\io\translators\bin\win32. • On UNIX: Run the HyperMesh results translator scripts, which are located in the directory [HyperWorks_install_directory]/altair/scripts. For CAE solver results files that HyperView does not directly support, you can translate them to a Hyper3D file or to a HyperMesh results file by using the appropriate HyperMesh result translator. To run a HyperMesh Results Translator • The command syntax for running a HyperMesh results translator is: translator_name [arguments] results_file output_file • To see a list of all available arguments for a results translator, run the command: translator_name -u • To create an H3D file from a HyperMesh results translator, specify the argument h3d in the command line. Exercise: Translate Results using HvTrans Step 1: Extract results from d3plot files using HvTrans. 1. From the Start menu, select Programs. 2. Select Altair HyperWorks / Tools / HvTrans. 3. From the File menu, select Open Result File. 4. Select and open the file d3plot from the truck folder. 5. Under Simulation, select By Step and increase By Step: to 2. 132 HyperView Introduction HyperWorks 9.0 Proprietary Information of Altair Engineering, Inc Chapter 10: Using HvTrans 6. Under Result Type, deselect all result types except for Stress (t). The result type displacement is not listed because displacement results are always written to the H3D file. 7. Under Options, leave Include model with translated results active and set it to From input deck. 8. Click Browse and select the model file truck.key. 9. Click Translate, specify the name d3plot.h3d for the H3D file, and Save. 10. From the File menu, select Exit to close HvTrans. 11. Open the saved file, d3plot.h3d, in HyperView.
