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:
  1. Variable visualization
  2. Velocity vector visualization
  3. Streamlines visualization
  4. Slice and Clip filters

Slide 4 :

System Requirement

To record this tutorial I am using
  • Ubuntu Linux Operating system 16.04 LTS
  • OpenFOAM version 4.1
  • ParaView version 5.0
Slide 5 :

Pre-requisite

To practice this tutorial, the user should have
  • Basic knowledge of Linux terminal commands
  • Experience with simulating cases in OpenFOAM
  • Working skills in ParaView

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
  • OpenFOAM has provided an inbuilt case file for pitzDaily.
Slide 7 : Problem Statement-Variable Visualization Here we will:
  • focus on post-processing of the pitzDaily solution
  • learn to visualize flow field variables like velocity, pressure, vorticity, etc.
  • learn to visualize velocity vector within the flow field
Slide You can find the pitzDaily case file within the simpleFoam directory within OpenFOAM-4.0>tutorials directory.


I have already copied this file in my work folder and run the simulation in my machine using simpleFoam.

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.


You will see all these files here.

Type paraFoam Now to post-process this simulation, type paraFoam, in the command terminal.


This will open the ParaView window.

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.


You will see the different types of Volume Fields available for visualization.


Here we will visualize the velocity field within the domain.

Check the U variable For this, check the U variable within the Volume Field.


Please note that the U variable is available to visualization, by default.

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.


This will show the initial flow conditions on the Graphic window.

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.


This will visualize the flow velocity field after 298 iterations.


Thus we have learnt to visualize field variables in ParaView.

Click on the Glyph filter >> point to the Pipeline window. After this we will learn to visualize velocity vectors.


To do this, click on the Glyph filter on the toolbar.


This will add a new component to the Pipeline window.

Scroll within the Glyph Properties panel. Now within the Glyph Properties panel make sure the
  • Glyph type is arrow
  • Scale Mode is off
  • Scaling Factor is 0.003


Keep the rest as default.

Click Apply button. Click Apply button on the top left corner of the Properties panel.


You will see small velocity vectors visualized within the domain.

Point to circulation zone and magnitude of velocity. You can now clearly see the circulation zone and magnitude of velocity.


Thus we have learned to create velocity vector in a flow field.

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:
  • focus on post-processing of the motorBike solution
  • learn to create stream lines and view them in ParaView
Terminal >> Visual Narration >> You can find the motorBike case file in the simpleFoam directory within OpenFOAM-4.1>tutorials directory.


I have already copied this file in my work folder.

And run the simulation using simpleFoam.

Terminal

Type cd ..

Type cd motorBike

Now open this solved case file in the command terminal.


Here I will type cd space dot dot

cd space motorBike

Type ls To see the content inside type ls


You will see all these files here.

Type paraFoam Now to post-process this simulation, type paraFoam in the command terminal.


This will open the ParaView window.

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.


You will be able to see the motor bike with the rider through the domain now.

Tool Bar >> click on stream Tracer filter To create streamlines around the motor bike, click on stream Tracer filter on the Tool Bar.


This will add a new component within the Pipeline browser.

Properties panel >>Seeds section >> change Point to (5 0 1)


Change Number of Points to 15


Change the Radius to 1

Here in the Properties panel change the Point to (5 0 1) coordinates within Seeds section.


This will change the location of the center of the stream lines.


Now change the Number of Points to 15.


This show the number of stream lines you want to create.


Change the Radius to 1.


This changes the radius of the stream line points.


Keep the rest of the values as default.

Click Apply After all changes have been made, click Apply on the Properties menu of the stream Tracer.


You can see stream lines around the motor bike along with their magnitude.


Thus we have learned to create stream lines in ParaView.

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
  • OpenFOAM has provided an inbuilt case file for hotRadiationRoom
Slide 11 : Problem Statement-Clip and Slice Filters Here we will:
  • focus on post-processing of the hotRadiationRoom solution
  • learn to use filters like clip and slice in ParaView
Terminal >> Open case file as per narration
  • To open the hotRadiationRoom case file
  • go to the hotRadiationRoom tutorial in BuoyantSimpleFoam within heatTransfer case directory.

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.


Now open this solved case file in the command terminal.

Type

cd /opt/openfoam4/tutorials/heatTransfer/buoyantSimpleFoam/hotRadiationRoom

Here I will type

cd /opt/openfoam4/tutorials/heatTransfer/buoyantSimpleFoam/hotRadiationRoom
