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.

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.

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.

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.
