|| '''OpenFOAM''' version 7 and  '''ParaView''' version 5.6.0

|- 
|| 00:18
|| This tutorial is recorded using:

'''Ubuntu Linux''' OS version 18.04

|- 
|| 00:25
||  A working '''Internet''' connection and  A '''text editor'''
|- 
|| 00:31
|| We will install '''OpenFOAM''' using the '''terminal'''.
|-
|| 00:35
|| Open a '''terminal''' by pressing '''Ctrl, Alt''' and '''T''' keys together.

|- 
|| 00:41
|| Make sure that you are connected to the '''Internet'''.
|- 
|| 00:45
|| A public key needs to be added to the '''repository'''. 

|- 
|| 00:49
|| This key enables the '''repository''' to verify '''OpenFOAM package signatures.'''

|- 
|| 00:55
|| To do this, in the '''Terminal''', carefully type the following '''command''' and press '''Enter'''.
|- 
|| 01:01
|| The machine will ask for the '''system password'''.

|- 
|| 01:05
|| Type the '''password''' and press '''Enter'''.
|- 
|| 01:09
|| Let me clear the screen.
|- 
|| 01:12
|| Now type the following '''command''' and press '''Enter'''.

|- 
|| 01:16
|| This will enable '''apt''' to search for '''dl.openfoam.org''' in the list of '''software repositories'''. 
|-
|| 01:25
|| Here onwards, please remember to press the '''Enter''' key after typing each '''command'''.
|-
||01:31
||Let me clear the screen. 
|- 
|| 01:34
|| Now type the following '''command''' to update the '''apt package''' list.
|- 
|| 01:39
|| The '''repository''' is updated.

|- 
|| 01:42
|| Next let us install '''OpenFOAM '''version 7.

|- 
|| 01:46
|| To do so, type the following '''command''' in the '''terminal'''.
|- 
|| 01:50
|| The installation may take some time depending upon your '''internet''' speed.
|- 
|| 01:55
|| The installation is done now.
|- 
|| 01:58
|| Let’s now configure the system to use the installed '''OpenFOAM package'''.

|-
|| 02:03
||Let me clear the screen.
|- 
|| 02:06
|| Open the '''.bashrc''' file located in the '''Home''' directory in a '''text editor'''.

|- 
|| 02:12
|| To do so, type the following '''command'''.

|- 
|| 02:15
|| I will be using the '''gedit text editor'''. 

|- 
|| 02:19
|| You may use any '''text editor''' of your choice.
|- 
|| 02:23
|| Scroll down to the end of the document.

|- 
|| 02:26
|| Add the following line of code as shown.

|- 
|| 02:30
|| This will enable us to execute the '''OpenFOAM commands''' via '''terminal'''.
|- 
|| 02:35
|| Save and close the file.
|- 
|| 02:38
|| Since the changes to '''.bashrc''' file is yet to be registered, we need to open a new '''terminal'''.

|- 
|| 02:45
||To open a new '''terminal''', press '''Ctrl, Alt''' and '''T''' keys together.
|- 
|| 02:50
|| In the new '''terminal''', type the following '''command'''.
|- 
|| 02:54
|| A message with the list of options is displayed on the '''terminal'''.

|- 
|| 02:59
||This confirms that '''OpenFOAM 7''' is properly installed.
|- 
|| 03:04
|| Let me clear the screen.
|- 
|| 03:07
|| Let us now check the installation of '''ParaView'''.
|- 
|| 03:11
|| Type '''paraview''' in the '''terminal'''.
|- 
|| 03:15
|| The '''ParaView''' interface opens in a new window.

Close the start-up screen.

|- 
|| 03:21
||This confirms that '''ParaView''' is properly installed.
|- 
|| 03:25
|| '''Close''' this window.
|- 
|| 03:27
|| The installation of '''OpenFOAM 7''' is now complete.

|- 
|| 03:32
