Data sources supported for post-processing scenarios

Load recipes

Load recipes define how to create boundary conditions and subcases in solutions.

For more information, see Load recipes.

Alternate representations of finite element models

• Mode sets

• Frequency response function (FRF) sets

• Acoustic transfer vector (ATV) sets

• Vibro-acoustic transfer vector (VATV) sets

Mesh information

Mesh information from the FEM or assembly FEM for certain scenarios, such as Contour Plots.

File formats and results

You can use scenario-based post-processing to visualize the following file formats and results. When you load certain file formats, you can set options for the data. For example, for an Abaqus .odb file, you can set the default units. The options you can set are shown in the table and explained in the next sections.

Data sources associated with pre-processing data

Data sources that you load through the Simulation Navigator are associated with the currently displayed pre-processing data. Associating the data sources with the pre-processing data lets you work with the underlying geometry in post-processing scenario contour plots. For example, you can select polygon edges and faces when identifying, graphing, annotating, or showing or hiding results. You can also choose to associate external data sources with the pre-processing data.

To associate pre-processing data with external data sources, select the Pre-Processing Groups and Meshes are Valid in Post check box in the Define Data Source dialog box.

A Simulation file that is valid for the data source must be the displayed or work part. A FEM or assembly FEM cannot be the displayed or work part.

Managing data sources with different formats

To support the different formats of .csv and .lms files, when creating a data source, the Select Data Source dialog box provides a Format list to let you select the format of the data source in addition to its path.

• CSV formats****GraphCsv — Contains curve data exported from XY Function Navigator. For more information about this format, see the Export Data dialog box. StiffnessCsv — Contains stiffness (read stiffness data (Frequency Response Functions (FRFs)) data. For more about the information about the format, see Stiffness CSV format for direct load identification.LMS formats****Test.Lab — Contains a Simcenter Testlab database. Tecware — Is a Tecware Universal file that contains transient series.

Maintaining the folder hierarchy

When you create a data source, you can select to maintain the folder hierarchy in the results files or flatten it. For example, if you organized the results per run for a Simcenter Testlab database, maintaining the hierarchy lets you find the data based on the internal file path.

If you ignore the folder structure, the software ignores the folder structure of the results and groups each type of data into one data definition. For example, if you organized the results per sensor in a Simcenter Testlab database, and you want to see all the data in the file, you can ignore the hierarchy and, therefore, decrease the levels.

Example:

In this example, a Simcenter Testlab database file contains the following folder hierarchy:

When you select to maintain the hierarchy (select the Hierarchy check box in the Select Data Source dialog box), the acceleration data listed in the Element node of Scenario Based Data-Visualization Navigator contains the name of the folders in the hierarchy. For example:

• Acceleration | Root | Section 1 | PG1 uneven road

• Acceleration | Root | Section 1 | PG2 bumps

Renaming channels

You can select to rename the channels in a data source. The channels are the types of data in the file. You can change them to be based on the standard Simcenter 3D Motion Solver variable names (for example, ax for Acceleration (X), x for Displacement (X)) or use the channel names from the data source. When you load a .csv file in Motion Excel 1 format or an .xls/.xlsx file, you can also select the worksheet and row that contains the channel names.

For example, if you select to use the standard variable names, the data listed in the Element node of Scenario Based Data-Visualization Navigator appears as follows:

• Root | ax | channels

• Root | axuc | channels

• Root | ay | channels

Unit of measure names

For a listing of measure names used for .csv files in Motion Excel1 format and xls/.xlsx files, see Unit of measurement names.

Note:

If a channel name uses an unsupported unit name (such as yard or day), that channel is considered unitless.

Upgrading Abaqus .odb files

When you create a data source from an Abaqus .odb file, the software updates the file to the latest supported version. You can select how you want to handle the file. For example, rename it, create a copy in the same or a temp folder, or overwrite the current version. The software creates a new file with a _v2020 suffix.

Visualizing multiple order cut and RPM data in post-processing scenarios

You can visualize multiple order cut and RPM data from the following types of data sources in post-processing scenarios, such as Campbell and waterfall plots:

• Universal (.unv) and Nastran punch file (.pch) in SORT2 format containing multiple RPM and/or multiple order results. For Universal files with multiple subcases and multiple RPM and/or multiple order results, the subcase names must be defined in the ID lines of data set 58. Note: SORT1 data from Universal files can only be displayed in post views.

• LMS (.lms) in SORT2 format containing multiple RPM results.

Where do I find it?

Application	Pre/Post
Prerequisites	A Simulation, FEM, or assembly FEM file as the work part and displayed part
Simulation Navigator	Right-click a node that can be used as a data source for post-processing, such as results, load recipes, mode sets, frequency response function sets, acoustic transfer vector set nodes, and so on, and choose Post-Processing Scenario
Scenario Based Data-Visualization Navigator	In the Data Sources node, right-click a data source→Plot and choose a scenario
