| Visual Cue | Narration |
| Slide 1 : Title | Hello and welcome to the spoken tutorial on Basic Post-Processing using ParaView. |
| Slide 2 : Learning Objectives | In this tutorial, we will learn some basic visualization techniques in ParaView. |
| Slide 3 : Learning Objectives | Under this we will learn:
|
| Slide 4 :
System Requirement |
To record this tutorial I am using
|
| Slide 5 :
Pre-requisite |
To practice this tutorial, the user should have
If not, please go through the previous OpenFOAM spoken tutorials on this website: https://spoken-tutorial.org/ |
| Slide 6 : Problem Statement-Variable Visualization | Variable visualization
|
| Slide 7 : Problem Statement-Variable Visualization | Here we will:
|
| Slide | You can find the pitzDaily case file within the simpleFoam directory within OpenFOAM-4.0>tutorials directory.
|
| Open a command Terminal. | Now we will open this solved case file in the command terminal. |
| Type cd /opt/openfoam4/tutorials/incompressible/simpleFoam/pitzDaily | Here I will type:
cd /opt/openfoam4/tutorials/incompressible/simpleFoam/pitzDaily |
| Type ls | To see the content inside this folder type ls.
|
| Type paraFoam | Now to post-process this simulation, type paraFoam, in the command terminal.
|
| ParaView Window >> click Apply | To visualize the domain geometry click Apply button.
This is on the top left corner of the Properties panel. |
| Graphic window >> | This will show the domain geometry on the Graphic window. |
| Scroll down >> point to the different types of Volume fields | Now scroll down within the Properties panel.
|
| Check the U variable | For this, check the U variable within the Volume Field.
|
| Go to the toolbar. | Now go to the toolbar. |
| Drop-down >>change vtkBlockColors to U | Change the vtkBlockColors to U from the drop-down options.
|
| Menu bar >> click the lastFrame button. | Now go to the Menu bar and click the lastFrame button. |
| Velocity field pattern | You can see the velocity field pattern of the converged solution.
|
| Click on the Glyph filter >> point to the Pipeline window. | After this we will learn to visualize velocity vectors.
|
| Scroll within the Glyph Properties panel. | Now within the Glyph Properties panel make sure the
|
| Click Apply button. | Click Apply button on the top left corner of the Properties panel.
|
| Point to circulation zone and magnitude of velocity. | You can now clearly see the circulation zone and magnitude of velocity.
|
| Close ParaView window | After this close ParaView window.
Now let us go back to the next problem statement. |
| Slide 8 : Problem Statement-Streamlines Visualization | Streamlines Visualization
OpenFOAM has provided an inbuilt case file for flow over a motorBike. |
| Slide 9 : Problem Statement-Streamlines Visualization | Here we will:
|
| Terminal >> Visual Narration >> | You can find the motorBike case file in the simpleFoam directory within OpenFOAM-4.1>tutorials directory.
And run the simulation using simpleFoam. |
| Terminal
Type cd .. Type cd motorBike |
Now open this solved case file in the command terminal.
cd space motorBike |
| Type ls | To see the content inside type ls
|
| Type paraFoam | Now to post-process this simulation, type paraFoam in the command terminal.
|
| ParaView Window >>click Apply in Properties panel. | To visualize the domain geometry, click Apply button on the top left corner of the Properties panel. |
| Menu bar >> click on lastFrame button | To include the last iteration, click on the lastFrame button on the Menu bar. |
| Tool Bar >> directional view >> +Y. | Go to the Tool Bar and set the directional view to +Y. |
| In drop-down >> Change vtkBlockColors to U | Change the vtkBlockColors to U from the drop-down options. |
| Scroll down Properties panel to Opacity | Now scroll down on the Properties panel to Opacity. |
| Reduce the Opacity | Reduce the Opacity to make the domain transparent like this.
|
| Tool Bar >> click on stream Tracer filter | To create streamlines around the motor bike, click on stream Tracer filter on the Tool Bar.
|
| Properties panel >>Seeds section >> change Point to (5 0 1)
|
Here in the Properties panel change the Point to (5 0 1) coordinates within Seeds section.
|
| Click Apply | After all changes have been made, click Apply on the Properties menu of the stream Tracer.
|
| Close ParaView window. | After this close the ParaView window. |
| We will go to the next problem statement. | |
| Slide 10 : Problem Statement-Clip and Slice Filters | Clip and Slice Filters
|
| Slide 11 : Problem Statement-Clip and Slice Filters | Here we will:
|
| Terminal >> Open case file as per narration |
You can find this within OpenFOAM-4.1>tutorials directory. |
| I have already copied this file in my work folder and run the simulation using BuoyantSimpleFoam.
| |
| Type
cd /opt/openfoam4/tutorials/heatTransfer/buoyantSimpleFoam/hotRadiationRoom |
Here I will type
cd /opt/openfoam4/tutorials/heatTransfer/buoyantSimpleFoam/hotRadiationRoom |
| Type ls | To see the content inside type ls.
|
| Terminal >> type paraFoam | Now to post-process this simulation, type paraFoam, in the command terminal.
|
| ParaView Window >> click Apply button | To visualize the domain geometry, click Apply button on the top left corner of the Properties panel.
|
| Scroll inside Properties menu | Now scroll down within the Properties menu.
|
| Volume Field >> check T variable >> click on Apply. | Here we will visualize the Temperature field within the domain.
|
| Toolbar drop-down >> change vtkBlockColors to T | Now go to the toolbar.
|
| Toolbar >> set directional view to +Z. | Go to the toolbar and set the directional view to +Z. |
| Menu bar >> click Play | Now go to the Menu bar and click Play button.
|
| Scroll Graphic window. | Now click and scroll on the Graphic window.
You can clearly see the temperature gradient due to radiation near the hot object.
|
| ParaView Window >> toolbar >> click on clip filter | First we will learn to create a sectional view of the field.
|
| Properties panel >> select Y Normal. | Now in the Properties panel select Y Normal. |
| Scroll Graphic window >> shift reference section | Scroll on the Graphic window like this. Then shift the reference section to the middle of the hot box. |
| Properties panel >> click Apply | After this click Apply on the Properties panel. |
| Toolbar >> change view direction to +Y | Now change the view direction to +Y on the toolbar.
|
| Delete this filter | Now delete this filter to visualize the full domain from the Properties panel. |
| ParaView Window >> toolbar >> click on slice filter | Now we will learn to create a planar view of the field.
|
| Properties panel >> select Y Normal. | Now in the Properties panel select Y Normal. |
| Scroll Graphic window >> toolbar >> change view direction to +Z | Scroll on the Graphic window like this.
|
| Graphic window >> shift reference section | Then shift the reference section to the middle of the hot box. |
| Properties panel >> click Apply | After this click Apply on the Properties panel. |
| toolbar >> change view direction to +Y | Now change the view direction to +Y on the toolbar.
|
| Close the ParaView window and switch to the slides | Close the ParaView window. |
| Slide 12: Summary | Let us summarize.
Under this we have learnt to
