Altair HyperLife 2025 Release Notes
Highlights
- Improvement to Stress Life evaluation to support scale factor output to achieve the required life for the given stress history.
- Improvement to Strain Life evaluation to support Standard Error of Cyclic Stress-Strain (SEc).
New Features
- Stress Life (SN) evaluation to Safety Factor = Scale
- In addition to the damage calculation, HyperLife evaluates the scale required to obtain a target damage or life, when safety factor is requested with option Scale.
- Strain Life (eN) evaluation supports Standard Error of Cyclic Stress-Strain
- The Standard Error of Cyclic Stress-Strain (SEc) is defined via the Strain Life material properties. The SEc value is calculated by modifying the cyclic strength coefficient.
Enhancements
- Launch Log file from Run Status
- HyperLife Run summary post evaluation can be directly launched from the Run Status dialog, by clicking the run name.
Resolved Issues
- Run name is now retained on reopening the Evaluate context and on reloading the session file.
- HyperLife preferences now reverts to default for number of processes.
- Empty H5 file written no longer when no rainflow output is requested.
- Assigning material to entity sets no longer shows application error.
- The number of processors from is now reflected in the .
Known Issues
- Material selection is not retained for the spot weld after weld fatigue analysis. The issue is inconsistent and will be fixed in the upcoming release.
- Layer should be manually selected for PERMAS H3D result file format for fatigue evaluation.
