    • 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.

    • 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.
