Post Processing

Use SnRD Post Processing tab to load and process the results.

The post-processing operation requires the model used for analyzing the squeak and rattle phenomena. Post-processing will require the solver deck (.FEM) exported from the pre-processing module. This solver deck is used throughout post-processing for creation of contour plots.

  1. Using the file browser option , browse and select the OptiStruct solver file and the pre output CSV file for the Model File and Pre-Output File selections.
    Note: SnRD will also look for the pre-output file and if present in the same folder as the solver file, it will be displayed in the Pre-Output File field. In case the pre-output file is not present in the same folder as the FEM file, a warning message will be displayed.
  2. Click under Results File(s) section.
    A file browser dialog opens.
  3. Browse and select the required .PCH and .H3D files.
    The selected file(s) are listed in the Results file(s) table.
  4. The solver results file(s) is scanned for subcases, if found subcases are listed in the Subcase Selection table.
  5. Click in Save Session File field.
    A folder selection is displayed.
  6. Browse and select the required folder.
  7. Name the session file and click Save.
    Once selected, SnRD will write out all the required session files to in the folder during the execution.
  8. Select the required analysis type for Analysis Type list.
  9. Select the required line from the Line(s) to analyze list.
    Tip: You can select individual line or select All lines in the model.
  10. Enter the value for % statistical evaluation.
  11. Select required radio button from Session Type options.
  12. Click Execute.
    Once execution is complete, a execution success message appears.

  13. Click Close.
    This process plots all the required data and graphs to analyze the squeak and rattle issues. Using the plotted results, you can perform the further post processing steps.
