    - Modal Participation
      Allows you to plot modal/panel participation curves from an OptiStruct .h3d file or an MSC Nastran .f06/.pch file.
    - Grid Participation
    - 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.
    - OrderCut 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
    - 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 Utility (HyperGraph 2D and HyperView)
      The Mount Optimization utility helps to predict 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.
