What's New

Selection of Frequency Range in Sine Sweep Fatigue

Frequency range selection is enabled for Sine Sweep fatigue events. With this update, the LoadMap context with Type of Loading: Sine Sweep allows a fatigue event to be defined with a single frequency of interest or a range of frequencies from the imported frequency response results.

Option to Skip Damage Calculation When Stress or Strain History is Requested

The Evaluate context supports the option to only output stress or strain history without calculating the damage for the given Stress Life or Strain Life evaluation. The feature is supported for both session-based or batch evaluations. The option is included in the Stress Strain history output within the Evaluate context > Advance Options.

Updates to Material Selection during HyperLife Batch Evaluation

HyperLife contains the following updates to material selection via batch evaluation.

• User-defined material XML path to be retained in the RunSetup XML.
• HyperLife evaluation errors-out if the assigned material XML is not found during batch evaluation.
• HyperLife evaluation skips the selected part/set if the material assigned is not available in the assigned material XML.
• Materials from the user-defined material XML assigned in the Run Setup file will not be copied to the HyperLife Material XML part of the HyperLife user-defined Material directory.

Additional Enhancements

• Performance improvement during solid element evaluation when stress gradient is included.
• Spot weld fatigue with transient results is extended to Radioss H3D. The support is extended to 1D spot welds only.
• Improvement to the total evaluation time when the Damage Summary CSV is requested for large entity sets in Stress Life or Strain Life evaluation.

• Strain life evaluation with entity sets using scale and offset in assign material context.
• Sine Sweep fatigue issue with multiple events and repeat count greater than one.
• Random Fatigue with nodal evaluation using ANSYS RST results.
• User warning is provided in HyperLife log file when assigned CSV for stress or strain history is missing.

The following known issues will be addressed in the upcoming release as we continuously improve the software:

• The FKM Mean Stress Sensitivity dialog in the Assign Material Context contains an issue with numerical precision.
