NVH Director 2024 Release Notes
Highlights
- A new option to rotate the results and recalculate MAC for axis-symmetric components.
- A new option to plot modal participation results for ERP.
New Features
- MAC for Axis-symmetric components
- A new option in the model correlation utility to specify the axis of rotation and angular increment value. This is useful to calculate correlation for symmetric modes for axis-symmetric components, for example, stator of electric motor. Symmetric modes are common in axis-symmetric components and chances of missing them in a test are often and likely. This feature allows to capture the correlation of symmetric modes correctly between a test and simulations.
- Radiated Sound-Modal Participation for ERP
- A new option in the Radiated Sound utility to plot modal participation for ERP. You can select the modal participation type from the result file and plot the participation for a single frequency or range of frequency.
Enhancements
- Model Correlation
- Enhancements to improve performance for MAC calculation for result files with solid elements.
- NVHD Dynamic LCS
- Enhancements to improve the usability for creation and editing of dynamic LCS.
Resolved Issues
- Issue related to creation of run matrix csv file in modal contribution utility for randomization studies.
- Issues related to handling of results in LCS in ODB file for MAC calculation.
