Altair HyperLife Weld Certification 2026 Release Notes

New Features

Assessment Method for Weld and Base Metal Evaluations in Specification Context
The Specification context facilitates selecting either Static or Fatigue calculation via the assessment method. This allows either static or fatigue evaluation with the events created in a load map in a single evaluation.
Single Results Report (CSV) Showing Input Properties and Output Results from Welded or Base Metal Evaluation
HyperLife Weld Certification supports a CSV report containing assigned input properties from the Points context or Material context and evaluated results based on the evaluation domain selected (welded or base metal) into a single file. The CSV report is generated for all elements or nodes that are queried during the Utilization report TXT generation. The report is written to the run directory created during the weld or base metal evaluation. The feature is supported for the following regulations in HyperLife Weld Certification: FKM, EuroCode 3, DVS 1612, and DVS 1608.
Base Metal Fatigue Evaluation is Extended to Parts Modeled with 3D Elements for FKM and EuroCode 3 Regulations
Base metal evaluation with EuroCode 3 and FKM in HyperLife Weld Certification is extended to solid elements. The evaluation considers exposed surface nodes of the solid part. The result files imported must contain corner-data stress for the evaluation as a prerequisite. The feature is supported for OptiStruct, Abaqus, and ANSYS result formats.
Base Metal Fatigue Evaluation of Parts Modeled with Shell Elements is Extended to Nodal Evaluation for FKM and EuroCode 3 Regulations
Base metal evaluation is extended to support nodal evaluation for shell parts. The feature requires corner-data stresses as a prerequisite from the imported result files.
Welded Static Evaluation Extended to Support 3D-3D Welded Joints
Static assessment of welds modeled with solid elements is supported for the following regulations: FKM, EuroCode 3, DVS1612, and DVS1608. The result files imported must contain corner-data stress for the evaluation as a prerequisite.

Enhancements

Static Evaluation for Welds to Display 1D Contour
Master 1D utilization contour is supported for a welded static assessment. The 1D contour reports the worst utilization for all evaluated locations of the weld segment.
Additional Enhancements
  • 3D-3D weld evaluation is extended to Abaqus and ANSYS models that contain corner-data stress.
  • Utilization report TXT and CSV report generate separate files when weld plus unwelded evaluation is chosen as the evaluation domain.

Resolved Issues

  • Base metal evaluation with FKM regulation assigned with constant amplitude loading.
  • Weld property file creating multiple tables upon import.
  • Inconsistency in reporting utilization results from Stress Life evaluation with solid elements.
  • Evaluate context not displaying Target Life for Stress Life - Safety Factor calculation.
  • Utilization values YY and XY interchanged in utilization report TXT upon query of 1D weld element.
  • Inconsistent application error with Stress Life or ERRI weld evaluation with some models.

Known Issues

The following known issues will be addressed in the upcoming release as we continuously improve the software:
  • Weld templates not listed in the specification context.
  • Unable to work with Stress-Life and ERRI session files in HyperLife Weld Certification.
The following known issue will be fixed in a future release as we continuously improve the software:
  • Inconsistency when evaluating solid welds with models containing both Shell and Solid components.
