Time Narration
00:01 Hello and welcome to the spoken tutorial on Installing and running OpenFOAM and paraView.
00:08 In this tutorial, I will show you:
00:11 How to install and run OpenFOAM , Paraview and
00:15 How to solve a Lid driven cavity case.
00:19 To record this tutorial, I am using:Linux Operating system Ubuntu version 10.04
00:26 OpenFOAM version 2.1.0, ParaView version 3.12.0
00:33 Note that OpenFOAM does not run on 'Windows' platform.
00:37 Also note, OpenFOAM v 2.1.0 is compatible with Ubuntu version 10.04 and above.
00:45 To practice this tutorial, you should have some basic knowledge of Computational Fluid Dynamics
00:52 and Linux commands.
00:55 Let me introduce you to OpenFOAM.
00:57 It is an Open Source Computational Fluid Dynamics Software.
01:02 It contains a wide range of solvers for solving CFD problems of 2 dimensions
01:08 as well as 3 dimensions.
01:11 Now, let me introduce you to Paraview.
01:14 It is used for visualizing the results obtained in OpenFOAM.
01:19 OpenFOAM and paraView can be installed through Synaptic package manager.
01:24 For Synaptic Package Manager, go to System > Administration > Synaptic Package Manager.
01:33 Type your password.
01:41 In the Search Box, type "OpenFOAM".
01:49 You can see openfoam as well as paraView.
01:54 Mark both of them for installation
02:06 and then click Apply to install.
02:12 The installation may take some time.
02:15 OpenFOAM and Paraview are installed.
02:21 For more details on Synaptic Package Manager,
02:25 please visit our website on this URL :http://www.spoken-tutorials.org
02:29 Alternately, you can also install OpenFOAM and paraView from the openfoam website on this url:

http://www.openfoam.com/download

02:38 Let me open up the browser.
02:45 In the browser URL, type : http://www.openfoam.com/download.

Press Enter.

03:10 Scroll-down and go to Ubuntu Deb pack. Let me zoom this.
03:23 Go to "Ubuntu Deb Pack Installation", click on it.
03:33 Let me zoom-out. Scroll-down and go to Installation.
03:40 From the first point of installation,
03:43 copy this command line and
03:46 paste it in the terminal window.
03:49 To open up a terminal window,
03:52 press Ctrl, Alt and t keys simultaneously on your keyboard or
03:59 go to Applications > Accessories > Terminal.
04:06 Open up a terminal window.
04:10 Now, copy this command line and paste it in the terminal window.
04:20 Note that in place of "lsb_release -cs",
04:26 replace it with the name of the Linux version that you are using.
04:30 Switch back to the browser. Above Installation, you can see different Ubuntu versions and the code names.
04:40 As I am using Linux 10.04,
04:45 I will replace "lsb_release-cs" with "lucid".
04:53 Open up the terminal window.
04:55 I will replace this by "lucid". Press Enter.
05:04 Note that installation here is incomplete.
05:08 If you follow the steps in the
05:10 sequence 1-2-3 and 4, you will be done through installing OpenFoam and paraView.
05:19 I have already installed OpenFOAM and Paraview through Synaptic Pacakage Manager some while ago.
05:27 Now we need to configure the installed software.
05:31 To do this, we need to edit the bash file.
05:35 Open a new command terminal.
05:39 In the command terminal, type : "gedit ~/.bashrc". Press Enter.
05:50 This opens up the bash file.
05:54 Let me drag this to the capture area, scroll-down to the bottom of the bash file.
06:05 Now, switch back to the browser.
06:09 Scroll-down and go to User Configration.
06:13 Look at the second point.
06:15 Copy this line and paste it at the bottom of the bash file.
06:25 Save it and close the bash file.
06:31 Now, we need to test the installed application.
06:35 To do this, open a new command terminal.
06:40 Let me drag this to the capture area.
06:49 In the command terminal, type: "icoFoam" (Note that 'F' here is capital) space -(dash) help
06:59 Press Enter.
07:03 A usage message will appear.
07:06 You are now ready to start with OpenFoam.
07:10 Now, let me show you how to set up a working directory.
07:14 Create a project or a user directory by the name "run".
07:21 Open a new command terminal. Let me drag this to the capture area again.
07:36 In the Command Terminal, type : mkdir (space) -p (space) $FOAM_RUN (note that 'FOAM' and 'RUN' are in capital). Press Enter.
07:55 Copy the tutorial directory from openfoam distribution to run directory
08:01 by typing on the terminal: cp (space) -r (space) $FOAM_TUTORIALS (space) $FOAM_RUN
08:18 (note that 'FOAM', 'TUTORIALs' and 'RUN' are in capital) and press Enter.
08:28 Both the directories are now created.
08:31 To view the directories, go to Places > 'Home' folder > 'OpenFOAM' folder.
08:40 You can see 'ttt-2.1.0', click on it.
08:44 Run and tutorials.
08:48 Close this.
08:51 Let me switch back to the slides.
08:56 If some error occurs during downloading OpenFOAM and Paraview,
09:00 from Synaptic Package Manager or Ubuntu Debian pack from the website,
09:05 then you can download and install OpenFoam and paraView from the source pack installation.
09:11 For source pack installation, go to the Download page of openfoam website.
09:18 Now, let me zoom this.
09:21 Scroll-down and go to "Source Pack Installation" . Now, click on this.
09:32 Now, scroll-down and go to Packs .
09:38 Download these 2 'tar' files and save them. I have already downloaded and saved these 2 'tar' files.
09:48 After this, go to your home directory.
09:51 To do this, go to Places > home folder.
09:56 Let me drag this to the capture area.
10:00 In your home directory, create a folder by a name of your choice.
10:09 Let me put this as 'abc'.
10:15 Copy the 2 downloaded files in the folder that you have just created.
10:20 To do this, copy these two 'tar' files and paste into the folder that you have just created.
10:37 Unzip or Untar these two files in the same folder. Extract here, this may take a couple of minutes.
10:47 After this, open a new command terminal.
10:51 In this, go to your home folder.
10:54 Type "ls" and press Enter.
11:00 Now, go to the same folder in which you have untared the tar files.
11:06 Now type: cd (space) abc and press Enter.
11:13 Now, to view the contents inside 'abc', type "ls" and press Enter.
11:24 Now, go back to the Download page of OpenFOAM website for source pack installation.
11:32 And, follow the steps given below for ubuntu distribution of OpenFOAM and Paraview.
11:39 We need to compile OpenFOAM and Paraview here.
11:43 It may take about 4 to 5 hours but this method always works.
11:50 Let us see how to solve a problem in OpenFOAM with an example.
11:56 Let me take a Lid Driven Cavity, as an example.
11:59 It is a 2D problem where the upper plate moves with a certain velocity and other three sides of the plate are fixed.
12:09 The type of Solver I am using here is for an incompressible flow called as "icoFoam".
12:17 Now, open a new command terminal again.
12:22 I will drag this to the capture area.
12:31 Type the path for the lid driven cavity problem.
12:35 Note that this problem has already been set up in OpenFOAM.
12:41 In the command terminal, type "run".
12:45 This will direct you to the run directory of OpenFOAM. Press Enter.
12:53 Now type: cd (space) tutorials , press Enter.
12:59 cd (space) incompressible, press Enter.
13:07 cd (space) icoFoam(Note that 'F' here is capital). Press Enter.
13:15 cd (space) cavity. Press Enter.
13:20 To view the contents inside cavity, type "ls" and press Enter.
13:27 You can see three files : '0', 'constant' and 'system'.
13:33 Now we need to mesh the geometry.
13:35 This can be done by the blockMesh utility of OpenFOAM.
13:40 In the terminal window, type: "blockMesh" (Note that 'M' here is capital). Press Enter.
13:52 Meshing has been done.
13:56 Now, run the solver 'icoFoam' by typing in the terminal "icoFoam" (Note that 'F' here is capital) and press Enter.
14:09 The iterations running can be seen in the terminal window.
14:13 Here, we notice that we have completed the solving point.
14:16 To visualize these results, let us open the paraview window.
14:21 To open paraView, type: “paraFoam” on the terminal (note that 'F' here is capital here). Press Enter.
14:42 This opens up the paraView window.
14:45 Now, on the left hand side,
14:48 in the object inspector menu,
14:50 click Apply to view the geometry.
14:54 You can see the Lid Driven Cavity.
14:57 Now, to see the boundary conditions, scroll-down the Object inspector menu and go to Mesh Parts.
15:08 Uncheck Internel Mesh and click Apply.
15:13 The geometry disappears.
15:15 Now, to view the moving and the fixedWalls,
15:19 check both the boxes and click Apply.
15:30 Now, uncheck the Movingwall and click Apply.
15:35 You can see the three fixed walls and the moving wall which just disappeared.
15:44 Thus we are done with running openFoam and paraView.
15:49 In future, we will come across more tutorials on solving and visualizing the OpenFOAM results.
15:56 Let me switch back to the slides.
16:01 In this tutorial, we learnt: How to install
16:05 OpenFOAM and Paraview through Synaptic Package Manager and the website and Solved a lid driven cavity.
16:12 As an assignment, install OpenFOAM and Paraview.
