NVH Director

NVH Director 2024.1 Release Notes

CAE Data Management and Versioning: New feature for CAE Data Management and File based versioning of Assembly XMLs and Representation files. Capability to version at multiple levels: team vs analyst, major vs minor. Access control with the possibility to assign roles to users for editing and/or viewing. Effective management of tracking up-to-date files and file conflicts with clear traceability of individual and team changes allowing the possibility to exchange data between different projects and/or previous versions.
External Acoustic Cavity Mesher: New option to create near field exterior acoustic cavity mesh with user chosen boundary layer supporting Infinite element or APML solver routine for prediction of exterior noise.

Internal Acoustic Cavity Mesher: Enhancement in the workflow for creating interior acoustic cavity mesh with context workflow driven options.
MAC Optimization: Enhancement to save the model file with optimized design variables.; Enhancement to show user message in case optimization run is not converted and optimized results are not available.; Enhancement to specify constrains for each mode pair.; Enhancement to allow you to restart the optimization run.
FRAC: Enhancements to Abaqus ODB result file for FRAC calculations.

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.
