Create data sources from external files

After you create a data source, it appears under the Data Sources node in the Scenario Based Data-Visualization Navigator.

Create a data source

1. In the Scenario-Based Visualization Navigator, right-click the Data Sources node and choose New Data Source from External File.Tip: You can also:Drag the file from an explorer to the graphics window when the Scenario-Based Visualization Navigator is displayed.Use the New Data Source from External File command at the bottom of the Scenario-Based Visualization Navigator.

2. Type the path and results name or click Browse to navigate to and select a results file.

3. To maintain the folder hierarchy of the results and use it to group the results into different data definitions based on the hierarchy, select the Hierarchy check box. If you clear the Hierarchy check box, the software ignores the folder structure of the results and groups each type of data into one data definition.For more information, see Maintaining the folder hierarchy and renaming channels.

4. (Optional) To associate the data source with the pre-processing data, select the Pre-Processing Groups and Meshes are Valid in Post check box. 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. 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.

5. Follow the steps for the following type of data source. Otherwise, continue with step 6. .cgns.csv.dac and .rsp.lms.odb.op2.pch.rst or .res.sc_h5.unv.xls/.xlsx

6. Click OK.

Create a data source from a .cgns file

1. Select the data source as described in Create a data source.

2. From the File Loading list, if the .cgns is a database, select which files to load. You can select to load:Only the selected fileAll the files in the folderAll subsequent files (time step)

3. From the File name separator list, select the separator used to divide the meta-ID of a file from its root solution name, either: **@Example: SolutionName@mesh.cgns_**Example: Fluid_Q_003881.cgnsThe software searches right-to-left for the first occurrence of the separator.

4. If the .cgns file does not contain unit information, in the Unit Systems group, set the mass, length, units, delta time, temperature, and angle units.

5. In the Evaluation Nodes group, type the names of the .cgns nodes that identify the pressure, mass density, speed of sound, temperature, velocity, and nodal area vector measure names.

6. Click OK.

Create a data source from a .csv file

1. Select the data source as described in Create a data source.

2. From the Format list, select its type. GraphCsv — Contains 2D plot data exported from Functions and Graphing. For more information about the 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.

3. Click OK.

Create a data source from a .dac and .rsp file

1. Select the data source as described in Create a data source.

2. To ignore the names of the types of data in the file (the channel names) and use standard Simcenter 3D Motion channel names, select the Use Standard Simcenter 3D Motion Channel Names check box.For more information, see Maintaining the folder hierarchy and renaming channels.

3. Click OK.

Create a data source from an .lms file

1. Select the data source as described in Create a data source.

2. From the Format list, select the type of .lms file. Test.Lab — Contains a Test.Lab database. Tecware — Is an LMS binary UNV file.

3. If you selected Test.Lab from the Format list, from the Hierarchy Level for Subcase, select the level to which folder names are concatenated to simulate subcases.

4. Click OK.

Create a data source from an .odb file

When you create a data source from an Abaqus database(.odb) file, the software updates the file to the currently supported Abaqus .odb version. You can select how you want to handle the upgrading of the file: rename it, create a copy of it in the same folder or a temp folder, or overwrite the current version. The software creates a new file with a _v2019 suffix.

1. Select the data source as described in Create a data source.

2. If the file is not the latest Abaqus version that the software uses, from the Upgrade Option list, select how you want to handle upgrading the file. Create a copy in the same folderCreate a copy in the temp folderOverwrite the fileRename the original file (adds a _original suffix)

3. If the .odb file does not contain default unit information, in the Unit System group, select the default length and mass units.

4. Click OK.

Create a data source from an .op2 file

1. Select the data source as described in Create a data source.

2. To specify the source of the .op2 file, which determines how the software reads the data, from the Format list, select one of the following:NastranOp2 — The .op2 file is from MSC or Simcenter Nastran. Default — The .op2 file is from another solver, such as GENESIS.

3. If the file does not contain default unit information, in the Unit System group, select the default units for length, mass units, temperature, and so on.

4. Click OK.

Create a data source from a .pch file

1. Select the data source as described in Create a data source.

2. From the Independent Type list, select the type of independent domain, for example, Frequency or Time.

3. If the .pch file does not contain default unit information, in the Unit System group, select the default length and mass units.

4. Click OK.

Create a data source from an .rst or .res file

1. Select the data source as described in Create a data source.

2. If the file does not contain default unit information, in the Unit System group, select the default length and mass units.

3. Click OK.

Create a data source from an .sc_h5 file

1. Select the data source as described in Create a data source.

2. If you want to expose functions on nodes, in the Expose functions on nodes if less than box, type a value.

3. Click OK.

Create a data source from a .unv file

1. Select the data source as described in Create a data source.

2. If the .unv does not contain unit information (dataset 164 is not in the file), from the Unit System group, select the default length and mass units.

3. From the Identifiers group, for datasets 55, 58, and 2414, specify the ID line from which to obtain the Name parameter for the function, subcase, and timestamp identifiers. You can select Line 1 through Line 5 of the function dataset or Not used. If you select Not used, the software ignores the parameter.

4. Click OK.

Create a data source from an .xls/.xlsx file

1. Select the data source as described in Create a data source.

2. To ignore the names of the types of data in the file (the channel names) and use standard Simcenter 3D Motion channel names, select the Use Standard Simcenter 3D Motion Channel Names check box.For more information, see Maintaining the folder hierarchy and renaming channels.

3. Click OK.
