Post-Process the Results

1. The results are automatically loaded into Autodesk Nastran In-CAD.
2. Right-click on Results and choose Edit.
3. Select STEP 40, Time=0.195 in the Subcases list and make sure the Deform Options and Contour Options checkboxes are selected.

   

4. Select DISPLACEMENT for Results Data under Contour Options. Make sure Max/Min is checked under Display Options. Click on Display under Plot, and then click OK to display the results.

   It may be necessary to edit the Default Settings, Display Options to show Max/Min Data on Contour.

5. The results should look like the image below.

   

6. Right-click on Total Nodes in the tree and select Query Display. This will allow you to look at the information on individual nodes by moving your mouse over them.

   

7. Move your mouse so that the node with the load is highlighted. Write down the Node ID; it will be used later to make an XY Plot of that particular node’s displacement.

   

   The Node ID might be different from the one shown in this tutorial.

8. Right-click on Total Nodes in the tree and select Query Display. This will disable the Query Display.
9. Right-click on Results and choose Edit.
10. Select SHELL MAX VON MISES 1/2 for Results Data under Contour Options. Click on Display, and then click OK to display the results.

    

11. The results should look like the image below.

    

12. Right-click on Results and select Multiset Animation Settings.

    

13. Change the End Set to STEP 62, TIME=0.305. Check the Deform Options checkbox only, uncheck all the other options.
14. Change the Mode setting to Half.

    

15. Click on the Animate button. This will load the animation. Click OK when done looking at the animation.
16. Right-click on XY Plot and select New.

    

17. For the Entity To Plot, make sure Node is selected, and under ID type in the Node ID you previously found.
18. For the Output Sets, make sure STEP 1, TIME=0.0 is selected for the Start Set, and STEP 62, TIME=0.305 is selected for the End Set.
19. For the Output Vector, make sure DISPLACEMENT is selected for Results Data, and select TOTAL for Component.
20. Click on the Show XY Plot button. The XY Plot dialog appears.

    

    

21. Click OK on the XY Plot dialog.
22. Now click into the ID input box field and select a node out in the center span of the wing. A new ID should appear, followed by a green square on the model indicating the node selected.

    

23. Change the Component from TOTAL to TY.
24. Click Show XY Plot.

    

    Other nodal quantities can be viewed such as acceleration, velocity, and forces.

This concludes Direct Transient Response of a Wing.

The following summarizes the main topics covered:

• Creating tables to be used for transient loading.
• Direct transient analysis setup, including structural damping and time steps.
• Using the nodal query display feature.
• Creating an XY Plot for total displacement.
