NVH Director 2023 Release Notes

Highlights

  • A new utility to post-process exterior noise results from OptiStruct calculated using Adaptive Perfectly Match Layer (APML) or Infinite Element (IE) methods. Options to review directivity plots, sound pressure level distribution and structural contribution for efficient root cause analysis and diagnostics of exterior noise problems.

New Features

Exterior Noise
New option of Exterior Noise in the Radiated Sound utility to post-process the exterior noise results from OptiStruct calculated using Adaptive Perfectly Match Layer (APML) or Infinite Element (IE) method. Option to plot the pressure results in the linear scale and octaves. For the selected frequency or octave band you can visualize directivity plots, sound pressure level distribution and structural contribution. These diagnostic capabilities are very efficient in problem solving exterior noise problems.
Ribbon Hints
Ribbon hints have been added to help identify tools that have multiple pick targets or open a secondary ribbon. They are small indicators that appear in the ribbon between a tool’s icon and label. The number of dots represents the number of pick targets in a tool, including some that are hidden until hovering over the tool.

To control this option, go to File > Preferences > Common > Application > Show ribbon hints.

Enhancements

CDTire
Enhancement to handle the camber and toe angles in CDTire creation.
Job Submission
  • Enhancement to submit jobs on Linux Operating System.
  • New option to allow custom script for job submission.
Deterministic Optimization
Enhancement to update the assembly with optimized design variable values from deterministic optimization OptiStruct Output. This new option allows you to load the vehicle assembly xml in the Assembly browser and update it with optimized variable values.
Network View
Enhancement to automatically arrange modules and connections in their respective positions in the vehicle coordinate system.
Workflow Improvements
  • Enhancements in workflow using new unity contexts to improve usability in creation and handling of Panels sets used in panel participation analysis and ERP.
  • Enhancement in assembly hierarchy modifications using drag and down of modules.

Resolved Issues

  • Issue related to performance in MAC calculation for a result file with a file size more than 15GB.
  • Issues related to modal animation in pretest.
