Altair HyperLife 2022.2 Release Notes

New Features

Strain History Output
Strain history can be output with EN analysis for a user defined set. The Advanced Options in the Evaluate tool is enhanced to reference a user defined Set or CSV file to output Stress or Strain histories in RSP format.
Enhanced Stress Strain History Output with Critical Plane
Stress and Strain history can be output for all the planes considered when stress combination approach is set to Critical Plane for both SN and EN analysis. The Advanced Options in the Evaluate tool is enhanced to reference a user defined Set or CSV file to output Stress or Strain histories in RSP format.
Event-wise Output in CSV Format
Damage results is output in CSV format for a user define set. The Advanced Options in the Evaluate tool is enhanced to reference a user defined Set or CSV file to output Event-wise Damage summary.
Evaluation Progress Bar in UI
Evaluation progress and summary of entities evaluated is displayed in the UI in the bottom left corner. This dynamic display can be used to understand the run progress after the job submission.
Common Preference Options
The Preferences (File > Preference) UI has been enhanced to expose General and other HyperView setting options for user modifications.
Static Failure Control Options for Stress Life Analysis
Static failure options are available under Advanced Options in the Evaluate tool. Available options are CONT, NOCHK, and STOP for SN curve as well as HAIGH diagram material model.
  • CONT: SN curve modified based on static failure check.
  • NO CHK: don’t check static failure.
  • STOP: stop evaluation of the fatigue event if static failure is reached.
Safety Factor Output Based on Constant Stress Ratio
Safety Factor output when stress ratio is constant (Stress Ratio = Constant) is available with Single and Multi Haigh diagram material models.

Enhancements

  • Menu options to specify Multi SN Curve Extrapolation and Multi Haigh Interpolation method is moved to the Evaluate tool under Advanced Options.
  • Material imports limitations when SR1 value lesser than UTS has been removed.
  • The run setup XML file is written in the working directory at the beginning of Fatigue evaluation. With this update, the XML file is written in the working directory as soon as the you click Run in the Evaluate tool.
  • Run Status UI has been updated to display a text message under Status instead of a static image to indicate the run progress.
  • Max Strain Value (MXLMSTRN) is exposed in the Material tool for Strain Life Uniaxial Analysis.

Resolved Issues

  • The user-defined Material XML file has been updated to incorporate the Others tab in the Material tool so that extra EN material parameters are retained on subsequent sessions.
  • Abaqus sets can now be imported in HyperLife.
  • Mean stress correction now works with Abaqus ODB.
  • The issue with mean stress correction while considering static subcase in Random fatigue has been resolved. User messages are issued to indicate missing element stress in any selected parts.
  • The Number of Processors can now be modified in the GUI.
  • User Sets created in the Model Browser now show in the Material tool.
  • Language and Recent Files now show in Preferences.
  • The issue with wrong Strain amplitude being reported when the Strain amplitude exceeded Max Stain in EN uniaxial is resolved.
