Visual Cue	Narration
Slide 1	Hello and welcome to the spoken tutorial on creating Curved geometry in OpenFOAM
Slide 2 : Learning Objectives	In this tutorial I will show you steps for creating a curved geometry in OpenFOAM. Viewing the results in ParaView.
Slide 3: System Requirement	To record this tutorial I am using Linux Operating system Ubuntu version 10.04. OpenFOAM version 2.1.0 ParaView version 3.12.0
Slide 4: System Requirement	The tutorials were recorded using the versions specified in previous slide. Subsequently the tutorials were edited to latest versions. To install latest system requirements go to Installation Sheet.
Slide 5: Hover over cylinder Hover over the geometry Hover over blocks break the circle into 4 parts	We will create a geometry for flow over cylinder. Note that I am using this case just for explanation. The cylinder is in a form of a semi circle. Meshing is a body fitted grid. The entire geometry is divided into blocks. We break the semi circle into equal number of parts. Now minimise this.
Open the lid driven cavity blockMeshDict file Hover over arcs	Open the blockMeshDict file of the previous tutorial. I have already opened it. Scroll down, for simple geometries you can see that edges is kept empty.
	Now create a new blockMeshDict file. To do this let us minimise this first.
On the desktop Right click > create document >create file	Now right click > Create document > Empty file
Name this as blockMeshDict	Name this as blockMeshDict. Note that M and D here are capital. Open this.
Copy the blockMeshDict of Lid driven cavity file from line 0 to line convert to meters	Now you can copy the initial few lines from the lid driven cavity upto convertTometers.
Copy these lines	Go up copy this upto convertToMeters.
Paste in the new blockMeshDict file	Copy this and paste it in the new blockMeshDict file.
Change the geometry to point one to one	Change the convert to meters from point one to one.
Geometry is in meters	As our geometry is in meters we will keep this as one.
Press enter	Now press Enter. Press Enter again.
Refer to the figure of flow over cylinder in slide 4	After this you need to enter the co-ordinates of the geometry in vertices. Let me switch back to the slides. Note that the points should be ordered in such a way starting from 0,1,2,3 and so on, as shown in the figure. Minimize the slides.
Type vertices after convertTometers	Now type vertices in the blockMeshDict file and press Enter.
	Insert an open bracket. Press Enter.
Enter the co-ordinates as shown in the diagram	Now enter the co-ordinates of points as shown in the diagram.
	Let me switch back to the slides.
Refer to the next slide for half semi-circle	For explanation I will use the right half of the semi-circle.
current blockMeshDict file	Enter the values for the points in the figure starting from zero. Let me switch back to the blockMeshDict file.
	Leave some space and enter the co-ordinates of point 0.
Point 0 - Insert (0.5 0 0)	Open close bracket and enter (0.5 (space) 0 (space) 0)
	Again leave some space, open close bracket.
Point 1- Insert (1 0 0)	Enter co-ordinates for point 1 (1 (space) 0 (space) 0) Press Enter.
	Leave two vertical spaces, again press Enter. Again press Enter.
	Leave some space and enter co-ordinates for the point number 4.
Point 4 – Insert (0.707 0.707 0)	Open close bracket, enter (0.707 (space) 0.707 (space) 0)
	Press Enter. Leave some space. Open close bracket.
Point 5 -Insert (0.353 0.353 0)	Enter the co-ordinates for point 5. Enter (0.353 (space) 0.353 (space) 0), press Enter.
	Now leave 4 vertical spaces.
	Enter co-ordinates for point number 9.
Vertical spaces	1 2 3 4 , again press Enter. Leave some space. Open close bracket.
Point 9 – Insert (0 1 0)	Enter (0 (space) 1 (space) 0), press Enter.
	Leave some space. Enter the co-ordinates for point number 10.
Point 10 -Insert (0 0.5 0)	Open close bracket (0 (space) 0.5 (space) 0), press Enter.
Remaining part of the semi-circle use the same procedure	Similarly enter the co-ordinates for remaining points in the geometry. Insert a close bracket and put a semi-colon Press Enter. Again press Enter.
In blockMeshDict file type blocks	Now type blocks and press Enter. Insert an open bracket and press Enter.
	Let me switch back to the slides.
Slide showing blocks	Block numbers are circled as shown in the figure.
	Now let me switch back to the blockMeshDict file.
Enter the type of block here	Leave some space. Enter the type of the block that is hex Leave some space.
Enter points for blocks	Now enter the points for the blocks. Open close brackets Leave some space. Open close brackets Leave some space.
SimpleGrading (1 1 1)	This simple grading can be kept as (1 1 1) and press Enter
Refer to the previous tutorial on simple geometry in openfoam	For creating the blocks please refer to the tutorial on Creating simple geometry in OpenFOAM. Note that there will be more number of blocks in this example.
Insert close bracket and semi-colon	Now insert a close bracket. Insert a semi-colon and press Enter. Again press Enter.
Type edges	In the next line, type edges and press Enter. Insert an open bracket and press Enter.
	Here you need to enter the points which are the end points of the arc.
Enter the arc points	Leave some space and type arc and leave some space. Type the points which are the end points of the arc. Let me switch back to the slides.
Insert end points of the arc From this slide	In this insert the end points of the arc. We start with 0 5. Let me switch back to the blockMeshDict file. Enter 0 space 5.
	Leave some space. Insert open close bracket.
	In brackets enter the co-ordinate of any intermediate point in between the two arc points. Now let me switch back again to slides.
Slide 6: for arcs	In the figure you can see that you have to pick up a point in between the two points of the arc.
	In this geometry I have picked up right half of the circle.
Slide showing trignometric relations Sin(theta) and cos(theta) relations	Using simple geometric relations, you can find the co-ordinates of the intermediate point shown in the semi-circle.
Repeat the above procedure for the remaining semi-circle	Similarly you can repeat the procedure for rest of the semi-circle geometry.
	Now let me switch back to the blockMeshDict file. Now press Enter.
	Note that there are more number of arcs in this example.
	Insert a close bracket. Insert a semi -colon and press Enter. Again press Enter.
In the next line after arcs refer to the tutorial on creating simple geometry in openfoam	Enter the boundary patches after arcs. Refer to the tutorial on Simple geometry in OpenFOAM for entering the boundary patches.
Enter boundary	Enter boundary, press Enter. Insert open-close bracket, press Enter. Insert close bracket semi-colon, press Enter. Again press Enter.
Type mergePatchPairs P here is capital	Now, in the next line type mergePatchPairs. Note that P here is capital.
	Press Enter. Insert an open bracket and press Enter.
	Since there are no patches to be merged, this can be kept empty. Insert a close bracket. Insert a semi -colon and press Enter.
Slide 7 : Points for the front face in the geometry	Let me switch back to the slides. Similarly enter the co-ordinate points for the points in the front face of unit thickness of the geometry, as shown in the figure.
Press Ctrl+Alt+t keys	Open a Command terminal.
Type run and press Enter. cd tutorials and press Enter cd basic and press Enter cd potentialFoam and press Enter cd cylinder and press enter	In the command terminal type the path for your case.
	I have already set the path for the tutorial case of flow over cylinder
Type blockMesh and press enter	In the terminal type blockMesh for meshing the geometry and press Enter. Meshing is done.
Slide 8: For OpenFOAM v 5.0 To open cylinder case directory, type the following in your run folder: $cd tutorials/basic/potentialFoam/cylinder To run Allrun script file, type: $./Allrun This will run blockMesh and potentialFoam commands.
Type paraFoam and press enter	Now type paraFoam in the terminal and press Enter to view the geometry.
	Let me drag this to the capture area.
In the object inspector menu click APPLY button	Now on the left side of object inspector menu click Apply. The geometry will be created as seen in the ParaView window.
	Scroll down the Object inspector menu.
Check and uncheck the mesh field box	Check and uncheck the Mesh field box.
Demo	You can see different regions of the geometry. You can also see the wire frame of the geometry.
For wireframe of the geometry Change from surface to wireframe	On top of active variable control menu in the drop down menu, change from Surface to Wireframe.
	You can see the wireframe model of the geometry. Close this. Let me switch back to the slides.
