Supported Files in HyperGraph 2D
HyperGraph 2D can read the following types of plot data files:
User Interface
The user interface provides you with a consistent look and feel when you are working in any of the HyperWorks Desktop applications.
HyperGraph 2D Menus
The HyperGraph 2D menus provide quick access to panels and tools.
HyperGraph 2D Toolbars
The HyperGraph 2D toolbars provide quick access to commonly used panels and tools.
Tab Area
The Tab Area is the portion of the graphical user interface that contains the browsers, utilities, and other functionality
not shown in the panel area.
Plot Browser
The HyperGraph 2D Plot Browser resides on a tab in the tab area sidebar and allows you to view the HyperGraph 2D plot structure.
NVH
From the HyperGraph 2D NVH menu, the following options are available.
Load the NVH Utilities Preferences File
Integrated Diagnostics
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.
Radiated Sound - Load
Load an H3D or PCH results file and plot a response for the Equivalent Radiated Power, Sound Power, or Sound Pressure result
types.
Radiated Sound - Display
After loading a file, use the Display tab to select a contour type and a concerned frequency.
Radiated Sound - Study
After plotting curves, perform a response study for Equivalent Radiated Power.
Global Modes
Identifies global modes from an OptiStruct or Nastran modal analysis.
Optimization, RBDO
Allows optimization of 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.
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.
Model Identification Tool
The Model Identification Tool, known as MIT, is a profile in HyperGraph 2D for fitting test data from frequency- and amplitude-dependent bushings to analytical models.
Tutorials
Discover HyperGraph 2D and HyperGraph 3D functionality with interactive tutorials.
HyperGraph 2D
Powerful data analysis and plotting tool for all types of CAE data.
HyperGraph 3D
HyperGraph 3D offers a 3-D plotting environment that is fully integrated with HyperWorks , for managing, reviewing, and analyzing 3-D plots such as waterfall, surface, and 3-D line data.
HyperGraph Solver Interfacing
The following sections describe support for various solvers in HyperGraph .
Plot a Response for Radiated Sound
From the Radiated Sound Load tab, load the result file to view and load the
model.
Make a selection from the Subcase drop-down menu.
Select a Result type from the drop-down menu: Equivalent Radiated Power, Sound
Power, or Sound Pressure.
If you select Equivalent Radiated Power:
From the Result component drop-down menu, select a panel.
Click Load Response to plot the response:
Linear/dB (Magnitude)
Linear/Octaves (Frequency)
The utility automatically switches to the Display tab.
If you select Sound Power for the result type:
For Result set, select Source Side or Receiver Side.
Click Load Response to plot the response.
The utility automatically switches to the Display tab.
If you select Sound Pressure for the result type:
For Result set, select Sound Pressure or Power from Pressure.
For Receiving Panels, select a set that corresponds to particular
source nodes. This can be used for panel participation.
For Result component, select the microphone location:
Select a node from list
Select the microphone location from model
Click Load Response to plot the response.
The utility automatically switches to the Display tab.
