HWD-0050: Translating Results - HvTrans

In this tutorial's exercise, Translate Results using HvTrans, 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

To open the HvTrans GUI

On Windows:
  • From the Start menu, select Programs > Altair 2021.1 > HvTrans 2021.1.
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.

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\win64
On UNIX:
  • Run the HyperMesh results translator scripts, which are located in the directory [HyperWorks_install_directory]/hm/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

Extract Results from d3plot Files Using HvTrans

  1. From the Start menu, select Altair 2021.1 > HvTrans 2021.1.
  2. From the File menu, select Open Result File.
  3. Select and open the file d3plot, located in the ../tutorials/mv_hv_hg/animation/truck folder.
  4. Under Simulation, select By Step and increase By Step: to 2.


    Figure 1.
  5. Under Result Types, deselect all result types, , and re-activate Stress by checking the corresponding box.
  6. Under Options, leave Include model with translated results active and set it to From input deck.
  7. Click Browse and select the model file truck.key.
  8. Click Translate, then specify the name d3plot.h3d for the H3D file, and then click Save.
  9. From the File menu, select Exit to close HvTrans.
  10. Open the saved file, d3plot.h3d, in HyperView.
