      • 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 or Deterministic approach.

      • Multiple Sample Analysis

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

      • Deterministic Optimization

        Reads results from an OptiStruct optimization run and processes the results to review the overlay of the NVH responses, baseline versus optimized. Compare changes in the design variable values, baseline versus optimized.

      • Display Options

        Customize plots using the following options

      • Filter Contributors

        Filters contributors to a smaller set of data.
