Scenario-based post-processing

Video: Analyze results using preconfigured views

Post-processing scenarios are preconfigured views that help you to visualize results, load recipes, acoustic transfer vectors, and more. Using the scenarios, you can select, filter, and shape the data into a format that is easy to interpret. For example, you can display a post-processing scenario as XY plots, color bar plots, color map plots, bar charts, 3D post views, or waterfall plots, depending on the scenario and your needs. The following figures show Motion results displayed as an XY plot and acoustic results displayed as a color bar plot.

You use the Scenario Based Data-Visualization Navigator to work with the scenarios.

For more information, see Using the Scenario Based Data-Visualization Navigator.

Types of post-processing scenarios

The following table lists the scenarios with a brief description of their uses. The scenarios that are available to you depend on the type of data. Only scenarios that use result files as input are available in Simcenter 3D Results Viewer.

Typical domain	Scenario	Example uses
General	Function Plots scenario	Visualize results in XY plots, color maps, color bars, waterfall, Campbell plots, and bar chart displays, and so on.
Contour Plots scenario	Visualize results as contour plots on a 3D meshed model, such as Simcenter Nastran OP2 SORT1 results.
Random Results scenario (Simcenter Nastran FEM acoustics and Simcenter 3D Acoustics BEM)	Visualize results from random analyses, both for structural and vibro-acoustic models.
Averaging scenario	Display results averaged for selected subcases, RPMs, orders, nodes, or DOFs.
Acoustics	Quality Metrics scenario	Assess the computational effort and contribution of an element order associated with a frequency response analysis using the Simcenter Nastran FEM Adaptive Order method.Visualize coupling quality results from Simcenter 3D Noise and Vibration MATV or ATV response solutions.

Data sources

Data sources contain the data to be displayed in scenarios. Data sources include results files, load recipes, acoustic transfer vectors, and more. For a complete listing of the data sources, see Data sources supported for post-processing scenarios. You can add data sources from the Simulation Navigator or from an external file.

Data sources are stored in the Data Sources node in the Scenario Based Data-Visualization Navigator. Abbreviations of the scenarios you can use to visualize a data source appear in the Value column.

You can also import a Simcenter 3D Results Viewer session file into Pre/Post to work with the same data sources and layouts.

Creating and editing a post-processing scenario

After you load a data source, the post-processing scenarios that support that type of data source appear in the Scenarios subpanel of the Scenario Based Data-Visualization Navigator. For example, the following scenarios appear for a Motion results file.

Select the post-processing scenario to display it in the graphics window in its default visualization, such as an XY or contour plot.

After you display a post-processing scenario, the post-processing scenario appears under the viewport node in the Scenario Based Data-Visualization Navigator and groups of options appear for setting up the scenario. You can use these options, for example, to specify fluid pressure, speed of sound, mesh source, response functions, contribution functions, and so on.

For more information, see Creating and editing post-processing scenarios.

Saving a post-processing scenario

You can save a post-processing scenario inside a layout state or Simcenter 3D Results Viewer session file. For more information, see Using layouts to save and restore views.

Note that a post-processing scenario is not saved as part of the Simulation or FEM part.

Creating templates for post-processing scenarios

You can use a layout state as a template to visualize post-processing scenarios. By using a layout state to create post-processing scenarios, you retain parameters and selections, and ensure consistency across results.

For more information about creating a layout state for post-processing scenarios, see Using layout states to replay post-processing scenarios.

Creating your own post-processing scenarios

Using NX Open and the User-defined Scenarios plugin mechanism, you can create your own post-processing scenarios to visualize results. You can write an NX Open program in any of the supported development languages, including Python, Visual Basic (VB), C++, C#, and Java.

The user-defined scenario appears in the scenario list in the Scenario Based Data-Visualization Navigator when a user loads a valid data source.

For more information, see User-defined post-processing scenarios.
