|-
| 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 in the '''terminal ''' '''cp (space) -r (space) $FOAM_TUTORIALS (space) $FOAM_RUN '''


|-
| 08:18
| '''(''' note  that '''FOAM''' '''TUTORIAL' And RUN'' are  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-210''', 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 errors 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 installationGo 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 this 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 file''' And '''paste''' it into the '''folder''' you just created

|-
| 10:37
| ''Unzip or Untar''' these two files in the same '''folder'''.


 ''' Extract here''', this make 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''' for '''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 '''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) tutorial '''(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 content 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

|-
|13:3
| This can be done '''blockMesh '''utility of OpenFOAM

|-
| 13:40
|Open the '''terminal window''' type '''blockMesh''' 


(Note here that '''M''' 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 we have '''completed''' the '''solving''' point.

|-
|  14:16
| To '''visualise''' these results let us open the '''paraview window.'''

|-
|  14:21
|  To open '''paraView''', type “'''paraFoam” '''in the terminal.


(Note that ''''F'''' is '''capital''' here)  press Enter

|-
| 14:42
|  This open ups 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 disappear.

|-
| 15:15
| Now to view the moving and fixedwalls


|-
| 15:19
| Check both the boxes and click Apply 

|-
|15:30
| Now uncheck the Moving wall   and click Apply

|-
| 15:35
| You can now see three fixedwalls and the moving wall which just disappeared.

|-
|  15:44
| As we are done with running openfoam and paraview

|-
|  15:49 
| In future we will come across more tutorials on solving and visualising the OpenFOAM result

|-
|  15:56
|  Let me switch back to the slides
