New Features

New Workflows for Notes, Measures, and Section Cuts in HyperWorks
The old panel-based workflow is replaced with a simplified guide bar for Notes and Measures and a micro dialog for Section Cuts. Also, all three tools have a dialog listing the measures/notes/section cuts for editing and managing these entities.

In addition to supporting existing functionality, the new Notes tool also offers additional features such as arrangement options, in-place editing, contour or component-based coloring, and rotation.

A brief description of each of these tools is provided below, for additional details please consult the User Guide.

The Notes tool user interface is now a guide bar and a Notes Review dialog that can be launched from the Results Ribbon. The guide bar provides you with the choice to either auto-create notes (by clicking on an empty area in the graphics or on any of the supported entities) or to manually select entities and create. In addition, the guide bar also has a preferences menu to set options such as note text, color, arrangement, and so on before creating notes.

Figure 1.

Figure 2.
Once the notes are created, you can edit the content of individual notes by double clicking and launching an in-place editor. The editor has options to attach a note to coordinates or to insert Templex expressions that will get evaluated during animation.

Figure 3.
You can also edit, manage, or delete notes by selecting them and using the right-click context menu.

Figure 4.
The right-click context menu provides many useful options:
  • New arrangement methods to quickly and automatically position the notes around the model. Once arranged, you can further adjust the note location by selecting and moving them on-screen.
  • Rotate the note text box.
  • Delete or Hide note(s).
  • Color note(s) based on a component color or a criteria such as contour value.
You can also manage or edit notes using the Notes Review dialog available via the satellite icon.

The Notes Entity Editor has few new attributes, such as specifying Notes text box position by screen location (in pixels) or model coordinates, setting text/border/fill color mode, specifying Rotation angle, and so on. Note: the Fit Model option will work on notes positioned by model coordinates.

The Measure tool user interface is now a guide bar and a Measures Review dialog that can be launched from the Results Ribbon. Set the measure type from the guide bar and depending on the type, you can either auto-create measures by simply clicking the entities in the modeling window or manually create measures by selecting entities first and then clicking the Create button.

Figure 5.
To edit measures, click on the satellite icon to launch the Measures Review dialog. Right-click on measure(s) and click on Edit to change measure attributes. The dialog also shows a preview curve of the measure by default and if needed, the curve can be placed on a separate HyperGraph window.

Figure 6.
Section Cuts
The Section Cut tool is now a microdialog and a Section Cuts dialog that can be launched from the View toolbar. The microdialog provides all of the options for modifying a planar or spherical section cut and the Section cuts dialog allows adding, bulk editing, or deleting section cuts and controlling the display of clipped geometry.

Figure 7.
Record and Playback for Exploded Views
HWC (HyperWorks Command language) coverage, which allows you to record and playback workflows in HyperView, has been expanded to support Exploded Views.
Tasks performed in this panel are recorded in the simple and intuitive HWC syntax and can be logged both in HWC or Tcl syntax on the file system. The command line supports auto-completion and interactive help and also allows easy modification and re-execution of commands.

Figure 8.
LS-DYNA Cross Sections Support
Cross Sections defined in a LS-DYNA input deck via *DATABASE_CROSS_SECTION can be read and visualized in HyperView. Both Planar and Set based Cross Sections are supported. For Planar Cross Sections, the plane and the associated part set can be displayed using three options: No Clip, Cross Section only, or Clipping Plane. For Set based cross sections, the underlying sets are displayed. Note: this entity is supported only in the new HyperWorks and not in HyperWorks Desktop. For full coverage and limitations, please refer to the User Guide.

Figure 9.
Unified Preferences Dialog in HyperWorks
HyperView preferences are now available in a harmonized dialog along with other HyperWorks clients. They will be available using the same entry point in the Menu bar File > Preferences. Image capture and H3D export-related settings are added to the common section of preferences, which apply to all HyperWorks clients.

Figure 10.
Failure Time Contour Plot in HyperView – Upfront Loader
A new result type, FailureTime, is now automatically available in HyperView – Upfront Loader for you to use to identify if and when an element will fail during the simulation.
The result type contains the following three components:
  • Value: Contour plot will show the time at which an element fails.
  • Frame: Contour plot will show the animation frame number at which an element fails.
  • Status: Contour plot will show whether an elements fails or not during the simulation.
Load all the animation steps and contour to view a plot as shown below.

Figure 11.

Note that the result file must contain Erosion (failed elements) data for the result type to be available.

Loading Progress in HyperView - Upfront Loader
Data Loading can now be monitored and/or cancelled in HyperView – Upfront Loader via a dedicated loading progress dialog. The dialog can be launched from the lower right corner of the status bar and shows the loading progress of both Loadcase/steps and result definitions.

Figure 12.


Entity Display Filter in HyperView – Upfront Loader
An entity selector is introduced in the contour/iso/vector/tensor plot guide bars in the HyperView – Upfront Loader profile. The purpose of the entity selector is to filter and display the plot on only a subset of the entities for which the definition has been loaded (which is typically all the components in the model).

Figure 13.
CAD Lighting Support
A new lighting option, Multi-light CAD, is now available and can be set from File > Preferences > Lighting.
Record and Playback Enhancements
  • Entity selection is now recorded for result scalar load operations.
  • New HWC command to capture active window to clipboard is introduced.
  • New HWC command to support switching of modes in an modal animation is introduced.
Section Cut Entity Enhancements
  • Line thickness of individual section cuts can be changed from the Section Cut Entity Editor. This is in addition to the previously existing global option under File > Preferences.
  • Gridlines can now be displayed for Deformable section cuts also.
Model Files Removed from Installation Package
To reduce the footprint size, the following tutorial model and demo model files are no longer included in the local installation. You can now find zipped tutorial model files and demo model files on Altair One via the Altair Community, Altair Marketplace, and Altair Connect sites. Altair recommends that you create an Altair One account and use it as your primary portal to access product documentation, a Knowledge Base, and customer support.
Tutorial Model Files
  • HyperView
  • HyperWorks
  • HyperWorks Collaboration Tools
  • HyperWorks Desktop
Other Enhancements
  • Two new APIs – GetFailureTimeList and GetFailureEntityCountList – are now available to get additional information on failed elements. Note that these are available in HyperView – Upfront Loader profile only. For further details, refer to the Reference Guide documentation.
  • Notes text boxes can be positioned by 3D coordinates, in addition to previously supported option of Screen position. Such notes will also be considered in a Fit Model operation.
  • Fit selected has been enhanced to work on selected notes. The operation will zoom and fit the entity attached to the note.

Known Issues

  • Segmentation error possible when working with a HyperWorks session containing HyperMesh and HyperView windows and using the Hotspot Finder.
  • In HyperWorks, if you start HyperView without cleaning your settings first and then switch to HyperMesh, the solver profile is not loaded properly, though there is a checkmark by it in the Solver Interface menu. This results in the loaded/available element types and full entity properties not being visible.

    Workaround: Select the solver interface from the Solver Interface menu (File → Solver Interface), even if it already appears selected, to manually load the profile.

Resolved Issues

  • Cross model measures are not restored in .tpl/.mvw files for measures resolved in a user system for modal complex/linear static models.
  • Incorrect layer options shown for 1D element strain result in the Build Plot panel.
  • Graphic artifacts (lines) seen when animating adaptive models with transparent selection highlighting on elements.
