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: |
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. |
