Generating CFD Plots/Streamlines - HV-3095


Generate cross sections for contour plotting of flow variables (for example, velocity or pressure)

Generate streamlines starting from a surface or line

Tools

To access the CFD Plot/Streamlines panel:

Click the CFD Plot panel button on the toolbar.

Or

Select CFD Plot from the Graphics menu.

This panel allows you to generate streamlines using any available nodal vector field (typically a velocity field). Velocity fields are directly written to H3D files by many solvers such as: Radioss, HyperXtrude, Moldflow, etc. Velocity fields and other scalar and vector data fields are also saved in EnSight format by most CFD solvers.

Exercise: Generating Streamlines and Cross Sections for ContourPlotting

This exercise uses the results file ensightb.case.

Step 1: Create multiple section cuts and contour the model.


ensightb.case as both the model and results files.

8. Return to the Section Cut panel .

9. Click the Add button.

10. Select Z Axis for the plane and click Apply.

11. Deactivate the section cuts by removing the check marks from their respective check boxes.

Note If the section cuts are not deactivated, the streamlines will also be cut and you would only be able to seethe points where the streamlines hit the cross section.

12. Return to the Contour panel .

13. Click the Clear Contour button.

Note If the contours are not cleared, all of the streamlines would appear gray and they would not be coloredaccording to the contour variable.



Step 2: Create a 'line' streamline.

1. Turn off the display of several components (BC3_wall ID 7, cells of cell type 1 ID 1, and cells of cell type 2 ID 2)using the Model Browser, so that the inside of the flow domain is displayed in the graphics area.

2. Select the CFD Plot/Streamlines panel from the toolbar .

3. Click Add, to add a new set of streamlines.

4. Select Line as the Rake type.

5. Specify N1 and N2 by picking two nodes on the BC1_inlet ID 4 component on the model.

6. Enter 10 into the Number of seeds text box.

7. Select Downstream from the Integration mode drop-down menu.



Altair Engineering

8. Click the Create Streamlines button (located in the lower right corner of the panel).

9. Under Display options, change the Streamline size to 7 and hit ENTER on the keyboard.

10. Activate the Draw as tube option.



Step 3: Create an 'area' streamline.

1. Add another streamline.

2. Select Area as the Rake type.

3. Select the BC1_inlet ID 4 component on the model.

4. Specify the Number of seeds as 40.

5. Select Downstream for the Integration mode.

6. Click Create Streamlines.


8. Select UVW(v) as the result type and click Apply.

9. Rotate the model and view the streamlines with the contour applied.



Querying Results

Querying Results - HV-4000


Query contoured results

Tools

To access the Query panel:

Click the Query panel button on the toolbar.

Or

Select Query from the Graphics menu.

The Query panel allows you to view and export properties, as well as other information, for all nodes, elements,components, and systems contained in the active model. Once the model has been contoured, you can also accessthe Query panel directly from the Contour panel by clicking on the Query Results button.

Exercise: Using the Query Panel


Step 1: Contouring the model and querying the results.




3. Contour the model for vonMises stresses.

4. Click Apply.



7. Select the Query panel from the toolbar .



Altair Engineering

8. Verify that the entity input collector is set to Elements.

9. Click the icon to deselect all items in the Option list.

10. Select the following four items in the Option list: Element ID, Contour(Stress), Load Case, and SimulationStep.

11. In the graphics area, pick a few elements on the model.

Observe the table in the panel shows the element id, the corresponding contour value, the load case, and thesimulation step for each of the selected elements.

12. Return to the Contour panel .

13. From the Averaging method drop-down menu, select Simple.

14. Click Apply.

15. Click on the Query Results button, located in the lower right hand corner of the Contour panel.

You are taken directly to the Query panel.

16. Verify that the entity input collector is set to Nodes.

Once the results are averaged, the values become nodal based and are no longer elemental based. This changeis reflected in the Query panel entity input collector.

17. Deselect all items in the Option list except for the following four items: Node ID, Contour (Stress), Load Case,and Simulation Step.

18. In the graphics area, pick a few nodes on the model.

19. Click on the Export button (located in the lower right corner of the panel), and save the table as query.csv.

The Export option allows you to save the data that you have queried as a .csv file, which can then be used for

further study, preventing the need to query the same data again.



20. Highlight a few rows in the table.

21. Right-click on the highlighted rows.

22. Select Copy from the list of available options.

You can now paste the copied rows into a text editor or a spreadsheet application.
