Model Export

Use the Export tool to export loadcases and variability studies.

Use the Export tool to export the prepared session to run analysis in OptiStruct. If a variability study is prepared, it can also be exported and processed using HyperStudy.
Before you export a model, all E-Lines of interest and a dynamic loadcase must exist in the model.
  1. From SnRPre ribbon, Analyze group, select the Export tool from the Run tool group.
    Figure 1.
    The Model Export dialog opens.
    Figure 2.
  2. Enter the file name.
  3. For Include File(s), select Preserve or Merge.
  4. Click Export.
  5. Browse and select the required folder.
    Note: During the solver file export, SnRD also exports E-Lines information to a CSV file. This file will be used in the post-processing of results.
    Tip: If you have not mapped material or GD&T data to E-Lines in the session, these can be manually updated in the CSV file after export and before post-processing.
    Restriction: If Include File(s) is set to Preserve, then all E-Lines and related information must be located main file. Post-processing is dependent on this.
    This will export the OptiStruct solver deck to the selected folder.
  • Model file(s) (.fem) along with a _preoutput.csv file are exported to the selected folder.
  • If Variability study is selected then, SnRD will also export the following:
    • .tpl file: Parametrized version of the model file.
    • .xml file: Study file containing HyperStudy setup.

Export Variability Study

If a variability study is created in the session, an additional export option is available to allow for export of a variability study session which can be opened in HyperStudy to run a Stochastics or DOE study or in batch mode.

  1. From SnRPre ribbon, Analyze group, select the Export tool from the Run tool group.
    Figure 3.
    The Model Export dialog opens.
    Figure 4.
  2. Select the Export Variability Study check box.
    Figure 5.
  3. Enter a name.
  4. For Loadcase, select the Dynamic Event to run in the study.
  5. For Number of Runs, define the number of runs.
    Note: The number of runs is automatically assigned by SnRD based on the number of studies and the number of variables. You can edit this value, but it is not mandatory.
  6. Select an analysis type.
  7. Select an option for Combine All.
  8. Click Export.
    The Job Submission dialog opens.
    Note: In the Job Submission dialog, you can export the variability to run in batch mode locally.
    Figure 6.


  9. Under Server Options, select JobSubmissionLocal.
    Important: Compose is required to perform the variability study in batch mode.
  10. For Run Options, define or edit any extra run options.
  11. Add comments.
  12. Click Submit Job.
Note: Use the open .xml file in HyperStudy to generate a run database and results required for DOE/Stochastics study.
The variability study TPL and XML files along with the OptiStruct solver file are exported to the selected folder.

Export Solver File Options

File Name
Solver file export name.
Include File(s)
Select exporting of include files.
Preserve: Preserves the data in individual include files along with their references in the main model.
Merge: The contents from the all include files are imported into the HyperMesh model but their references are not maintained. When exporting, all entities are written into the main file.
Pre Output CSV
CSV file containing the E-Lines definition.
