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
16:01	In this tutorial we learnt how to install:
16:05	OpenFOAM and Paraview through Synaptic Package Manager and the website solved a lid driven cavity.
16:12	As as Assignment, install OpenFOAM and Paraview
