Altair HyperLife Crack Growth 2025.1 Release Notes

New Features

Import/Export of the Crack Growth Run Setup File (XML)
HyperLife Crack Growth supports import and export of the run setup file (XML). The feature is supported via File Options, enabling you to import the crack growth session pertaining to Material, Loadmap and Hotspot contexts.
Hotspot Context to Allow Stress Selection Along Crack Direction
Selection of required stress distribution along the crack direction is supported. The Hotspot contexts lists “Stress Distribution” with the options Auto, YY, ZZ and Absolute Maximum Principal. Based on local coordinate system defined at the hotspot, you can select the required stress along crack direction. The Hotspot XML is also enhanced to show selected stress distribution for batch-based evaluation.
Penny Shape Crack Type
Penny Shaped Crack type is added to the list of supported 1-dimensional weighted function crack types.

Enhancements

Updates to Crack Direction
The crack direction defined via the local coordinate system at the hotspot will always be the local X axis as compared to local Z axis in the previous versions. If a local coordinate system is not defined, for example if Crack Direction is set to Normal, the crack direction will be in local X and stress distribution is along the XZ plane. If Crack Direction is set to User Defined System, crack direction is along the local X and stress extracted along crack direction is as per the stress option selected in Stress Distribution. The changes are in accordance with the images highlighted in the Hotspot context for the selected crack type.

Resolved Issues

  • Issues concerning the LoadMap Context for event definition, Apply to All and Ctrl+A have been resolved.
  • The issue concerning the LoadMap Context for duty cycle importing incorrectly has been resolved.
  • Unable to import systems assigned to Hotspots via HyperLife Crack growth session file has been resolved.
  • Batch run requiring a user message when no parts are assigned in a batch run has been supported.
  • Inconsistent issue concerning some models not showing stress distribution after the first point in crack direction has been resolved.
  • An issue with Run Setup XML dependent on the full path of the model and result file during batch evaluation has been resolved.

Altair HyperLife Crack Growth 2025 Release Notes

Highlights

  • Updates to crack growth evaluation via batch evaluation and event group support.
  • Event contribution XML is now output for additional results in post-processing.

New Features

Batch evaluation Support
Support for HyperLife Crack Growth evaluation in batch. The run setup XML housing the hotspot XML is utilized as batch input for evaluation. Batch evaluation is supported on both Windows and Linux.
Support of Nested Events
HyperLife LoadMap introduces “Event Groups” for the Crack Growth profile to define combination of events within events. Repeats can be applied to the events and the event groups to obtain the required sequence of loading in the duty cycle. Event Groups support is also extended to HyperLife LoadMap XML.
Support of Event Contribution
For the duty cycle assigned to the crack growth evaluation, the percentage contribution of each event to the crack growth history are output as results to the run directory. An event summary CSV is output for each evaluated hotspot if more than one hotspot is chosen for evaluation.
Support of Min and Max Stress in the Duty Cycle
The maximum and minimum stress from the entire stress history of the duty cycle is output via a CSV, post crack growth evaluation.

Resolved Issues

  • An application error when trying to close a load history plot has been resolved.

Known Issues

The following issues will be addressed in the upcoming release:
  • Right click menu options Apply value to all events and Apply value to current event from LoadMap event creation are not working as intended; the issue will be fixed in the upcoming release.
