      • Load an NVH Utility

      • Integrated Diagnostics

        Calculate a response, perform contribution analysis, plot results, and perform diagnostic studies and study response changes.

      • Modal Participation

        Plot modal/panel participation curves from an OptiStruct .h3d file or an MSC Nastran .f06/.pch file.

      • Grid Participation

        The Grid Participation utility allows you to plot panel grid participation results and then use advanced scaling contour capabilities to isolate key contributing areas.

      • Energy Distribution

        Visualize the distribution of energy within a full vehicle NVH model, as a way to understand what components are dominating the vehicle response.

      • Transfer Path Analysis

        Identifies the complex contribution of the excited structure through attachment points to a response in the responding structure.

      • Design Sensitivity Analysis

        Design sensitivity represents a change in response with respect to a change in a design variable, which is typically used for optimization.

      • Order Analysis

        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.

      • Modal FRF

        Calculate a frequency response based on modal results.

      • Model Correlation

        The Model Correlation utility determines the degree of similarity or correlation between two sets of results.

      • Radiated Sound

        The Equivalent Radiated Sound utility post-processes the results of exterior structure-borne radiated sound.

      • Global Modes

        Identifies global modes from an OptiStruct or Nastran modal analysis.

      • Flow Induced Noise/General Signal Processing

        The General Signal Processing utility processes the time domain pressure results from CFD simulations and visualizes the results in both the time and frequency domain.

      • 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.

      • Optimization, RBDO

        Optimizes sensitive parameters for multiple sample analysis results using the RBDO approach.

      • Multiple Sample Analysis

        Post-process results from a Multiple Sample Analysis, including plotting a spread of responses (+/-95% and mean).

      • Display Options

        Customize plots using the following options

      • Filter Contributors

        Filters contributors to a smaller set of data.
