Stress Manipulation

Derive results based on the effective stress or selected stress type.

The Stress Manipulation tool simplifies/automates the derivation of additional, geo-meaningful results (scalars, ratios and in-plane stresses from tensors) based on the effective stress or any other user selected stress type. Additionally, it converts stresses from engineering to geological convention.
Figure 1.
Note:
  • It is recommended that the input file contains effective stress results.
  • The model and results file must have Abaqus naming conventions e.g. *.odb or *.h3d file created using the Results Conversion tool.
  • The loading of the model and result files can be done either before or after the launching of the tool.

Stress Manipulation

  1. Select the Stress Manipulation tool from the Select GeoD Tool drop down list.
    Figure 2.
  2. Click the Load Model from the Task table.
    Figure 3.
  3. Select the Load Model and Load Results check box and browse and select the required model and results files and click Apply.
    The model and result files are loaded in the HyperView window.
  4. Click Next to move to the next step in the process.
  5. Click Select inputs task.
    Figure 4.
    The Select inputs panel is displayed.
    Figure 5.
  6. Select the required sub case check box from the Subcase table.
    Note: Once the user selects the subcase, all the other sections are activated.
  7. Click the Select All button.
    All available subcases in the table are selected.
  8. Click the Select None button.
    All subcases are deselected.
  9. Click the Select Reverse button.
    Subcase selection is reversed.
  10. Select the required simulation from the Simulation table.
    Figure 6.
  11. Select the required stress components from the Derive Results Based On table.
    Figure 7.
    Note: By default, the global stress with IP-Effective (Integration Point) is selected. The user can select any one stress type for deriving additional results.
  12. Select the required results from the Results to Propagate table to propagate into the new h3d file.
    Figure 8.
    Note: The user can propagate the results from ODB file to H3D file by selecting the results from the Results to Propagate table. Uncheck the results that are not required to be propagated (copied) into the new h3d file.
  13. Click the Components button.
    The Extended Entity Selection window is displayed.
    Figure 9.
  14. Select the component by any method in the Extended Entity Selection window.
  15. Click the Displayed button adjacent to the Components button.
    Figure 10.
    The components is highlighted in the graphics area.
  16. Click All to select all the components of the model.
  17. Click Reverse to reverse the component selection.
  18. Click Clear Collector to reset or clear the component selection.
  19. Click Next to move to the next step in the process.
  20. Select the required results from the Standard Results table.
    Figure 11.
    Note: By default the Principal stress is selected.
  21. Select the required results from the Derived Scalars table.
    Figure 12.
    Note: By default the Mean Stress stress is selected.
  22. Select the required results from the In-Plane from Tensor table.
    Figure 13.
  23. Select the required ratios from the Ratios table.
    Figure 14.
  24. Click the file browser button in the Output file text field.
    A file selection window opens.
  25. Browse and select the destination folder and click Save.
  26. Click Generate H3D.
    An information message is displayed.
    Figure 15.
    Note: The H3D file is generated using HV Trans result translator.
    Once the H3D file is generated, a confirmation window is displayed.
    Figure 16.
  27. Load the newly created h3d file, after the completion of the process into HyperView window along with the other propagated results.
    Figure 17.
