NVH Menu
The NVH menu provides you with access to various NVH utilities.
- NVH Integrated Diagnostics Utility (HyperGraph 2D)
- NVH Modal/Panel Participation Utility (HyperGraph 2D)
  Allows you to plot modal/panel participation curves from an OptiStruct .h3d file or an MSC Nastran .f06/.pch file.
- NVH Grid Participation Utility (HyperView only)
  The Grid Participation utility allows you to plot panel grid participation results and then use advanced scaling contour capabilities in HyperView to isolate key contributing areas.
- NVH Energy Distribution Utility (HyperGraph 2D)
  Visualize the distribution of energy within a full vehicle NVH model, as a way to understand what components are dominating the vehicle response.
- NVH Transfer Path Analysis Utility (HyperGraph 2D)
  Identifies the complex contribution of the excited structure through attachment points to a response in the responding structure.
- NVH Design Sensitivity Analysis (DSA) Utility (HyperGraph 2D)
  Design sensitivity represents a change in response with respect to a change in a design variable, which is typically used for optimization.
- NVH Order Analysis Utility (HyperGraph 2D)
  Generates and post-processes engine order related data from an OptiStruct or Nastran frequency response analysis that contains either RPM-based loading subcases or order-based loading subcases.
- Model Correlation Utility (HyperView and HyperGraph 2D)
  The Model Correlation utility determines the degree of similarity or correlation between two sets of results.
  - Access Model Correlation in HyperView
  - Modal Assurance Criterion (MAC)
    Modal Assurance Criterion (MAC) is a measure of the correlation between two vibration shapes.
  - PreTest
    PreTest allows prediction and optimization of the sensor locations (accelerometers) for measurements and directions along with test excitation point location, a very important step in the experimental modal analysis process directly affecting the accuracy of test results. Driving point residue (DPR) calculation gives information on optimum point for excitation location.
  - Frequency Response Assurance Criterion (FRAC)
    Frequency Response Assurance Criterion (FRAC) is a measure of the correlation between two frequency response functions (FRFs) representing the same input-output relationship.
    - FRAC - Load Tab
      The FRAC utility's Load tab allows you to select and load the reference and correlation files to prepare them for a FRAC analysis.
    - FRAC - Display Tab
      The FRAC utility’s Display tab allows you to filter FRAC results and select various plotting options using the FRAC and FDAC sub-tabs.
- Mount Optimization
  Predicts powertrain rigid body mode frequencies and kinetic energy distribution, which play a critical role in optimizing the mount stiffness and layout configuration, by decoupling powertrain rigid body modes and reducing vibration transmission.
Vehicle Safety Tools
The Vehicle Safety Tools (VST) is a collection of over 200 macros, Templex functions, and external functions for use by a vehicle safety engineer.
Upfront Data Loader
A new workflow emphasizing upfront data loading for standard crash post processing use cases.
