Aerospace 2022.3 Release Notes

No updates were made to Aerospace in 2022.3.

Altair Squeak and Rattle Director 2022.3 Release Notes

Highlights

  • Part of Ziegler Database packaged within SnRD - Offline.
  • Risk Assessment Results are available in E-line Review Table.
  • A Shorter version of the E-line ID can now be visualized Barplot in Risk Assessment

New Features

Risk Assessment Results are Available in E-line Review Table
The maximum value for each E-line of the visible results type and load case is shown in the E-line Review table. This allows for easier comparison of E-line risks and makes it possible to remove No/Low risk E-lines from the model to reduce scope for further investigations and diagnostics.

Enhancements

Part of Ziegler Database Packaged Within SnRD - Offline
Ziegler PEM Database can be used to perform a material compatibility analysis or to extract the Impulse rate range for a material pair, which is required for Squeak evaluation. For extraction of Impulse Rate only, you can use the direct integration inside of SnRD. In this release, it has been taken offline and no connection to the cloud based data is required.
A Shorter Version of the E-line ID Can Now be Visualized in the Barplot in Risk Assessment
To avoid cluttering the barplot axis, you can now decide to show only the short version of the E-line ID, excluding the numbering convention for the number of E-points on the E-line.

Resolved Issues

  • Connection to Ziegler PEM Database for Squeak E-line material mapping is available again in this release.
  • Coordinate System was not correctly created when creating E-lines using Manual Method (selecting Main/Secondary manually), this is now resolved.

Known Issues

The following known issues will be addressed in future releases as we continuously improve performance of the software:
  • Pre: contour plots for multiple load cases cannot be shown at the same time in the window.
  • Post: comparing Squeak results from multiple load cases is not supported.
  • Post: comparing multiple load cases from different files with same load case ID is not supported.
  • Post: combined loading with a model which only consists of Squeak lines is not supported.
  • Post: loading a model file from a network location (unless it’s mapped to a drive) is not supported.

NVH Director 2022.3 Release Notes

Highlights

  • Update NVHD Assembly with optimized design variable values from deterministic optimization OptiStruct output.

New Features

Update NVHD Assembly with optimized design variable values
New option in the Assembly to map and update the assembly with optimized design variable values from deterministic optimization OptiStruct output. This new option allows you to read a mapping file (CSV file) having information on the design variables and their optimized values from OptiStruct output. You can choose the design variables and review them and update the assembly with new optimized values. This information is then saved in an XML file for reuse and further iterations.

Enhancements

CDTire
  • Enhancement to support create CDTire from the latest version 2021.1.1 of the CDTire Parameter file.
  • Enhancement to automatically identify the width of patch points from the CDTire parameter file.
  • Enhancement to create CDTire, by default, with rotation in counterclockwise direction and corresponding changes in the delay calculation to simulate the condition of the vehicle moving in forward direction.
Workflow Improvements
  • Enhancements in workflow using new unity contexts to improve usability in creation and handling of control volume
Modal FRF
  • Enhancement in LCS creation workflow using enhanced core options for LCS creation

Resolved Issues

  • Issue related to derived responses calculation in Modal FRF for FRF responses starting from zero Hz.
  • Issue related to additional windows creation on clicking on the screen when transformation is in progress in Modal Assurance Criteria.

Safety Tools

Enhancements

IP Impact Post Processing Tool
Support of Pamcrash solver:


Figure 1.

Resolved Issues

  • IP Impact Pre-processing Tool:
    • Pamcrash: Correction of exported set in the impactor positioning file to avoid duplicated nodes.
    • When marking the IP with Automatic marking process, the move back angle value on the impact points is now set to 0.3 degree.
  • Seatbelt tool:
    • Radioss: Correction of the density value in the default /MAT/FABRIC when unit system (mm, s, Mg) is selected.
    • Radioss: Seatbelt tensioning is now working when dummy is encrypted.
  • Mechanism and Dummy:
    • Import of model having duplicated IDs in Mechanism and Dummy metadata has been corrected.
