| '''OpenFOAM''' માં વક્ર જોમેટ્રી બનવાના આ સ્પોકન ટ્યુટોરીયલમાં સ્વાગત છે.

|-
| 00:06
| આ ટ્યુટોરીયલમાં હું તમને બતાડીશ.

|-
| 00:09
| '''openfoam''' માં વક્ર જોમેટ્રી બનાવવાના સ્ટેપ.

|-
| 00:14
|Viewing the results in અને '''paraview''' માં પરિણામોને જોવું.

|-
| 00:17
| આ ટ્યુટોરીયલ રિકોર્ડ કરવા માટે, હું વાપરી રહ્યી છું,

|-
| 00:19
| '''Linux Operating system Ubuntu આવૃત્તિ 10.04'''. '''OpenFOAM આવૃત્તિ 2.1.0 '''

|-
| 00:28
|'''ParaView આવૃત્તિ 3.12.0 '''

|-
| 00:32
|We will create a '''geometry''' for ''' cylinder'''. આપણે ''' cylinder''' પર ફલો ના માટે જોમેટ્રી બનાવીશું.

|-
| 00:36
| નોંધ લો કે હું આ કેસ ફક્ત સમજુતી માટે ઉપયોગ કરી રહી છું.

|-
| 00:41
|The '''cylinder '''is in a form of a '''semi circle.'''

|-
| 00:45
|'''Meshing''' is a body fitted grid.

|-
| 00:49
|The entire '''geometry''' is divided into blocks.

|-
| 00:54
|We break the '''semi circle''' into equal number of '''parts'''.

|-
| 00:58
|Now minimise this

|-
| 01:03
| Open a '''blockMeshDict '''file of the previous tutorial

|-
| 01:08
|I have already opened it

|-
| 01:12
|Scroll down, for '''simple geometries''' you can see that '''edges '''is kept empty

|-
| 01:20
| Now Create a new '''blockMeshDict''' file

|-
| 01:23
|To do this let us '''minimise''' this first

|-
| 01:27
| Now '''Right click > create document > empty file'''

|-
| 01:34
| Name this as '''blockMeshDict'''.

|-
| 01:40
|Note that M and D here are capital

|-
| 01:46
|Open this

|-
| 01:51
| Now you can copy the initial few lines from the '''lid driven cavity''' upto '''convertTometers'''

|-
| 01:58
|Go up '''copy''' this upto '''convertToMeters'''

|-
| 02:04
| '''Copy this''' and '''paste it''' in the new '''blockMeshDict''' file

|-
| 02:12
|Now change the '''convert to meters''' from '''point one to one'''

|-
| 02:18
| As our '''geometry''' is in '''meters''' we will keep this as one

|-
| 02:24
| Now press '''enter''' , press '''enter''' again

|-
|02:28
| After this you need to enter the '''co-ordinates''' of the''' geometry''' in '''vertices'''

|-
| 02:35
|Let me switch back to the slide. Note that the points should be ordered in such a way starting from '''0,1,2,3, 4''' and so on. as shown in the figure

|-
| 02:47
| Minimise the slide. Now type '''vertices''' in the '''blockMeshDict''' file and press '''Enter'''

|-
| 02:56
| Insert the open bracket and Press '''Enter'''

|-
| 03:00
| Now enter the '''co-ordinates''' of a geometry as shown in the '''diagram'''.

|-
| 03:05
| Let me switch back to the slides

|-
| 03:08
| For explanation I will use right half of the semi-circle

|-
| 03:12
| Enter the values for the points in the figure starting from 0

|-
| 03:16
|Let me switch back to the '''blockMeshDict''' file

|-
|03:20
| leave some space and enter the '''co-ordinates''' of '''point 0'''

|-
| 03:27
| Open close bracket enter '''0.5 (space) 0 (space) 0'''. Press Enter

|-
| 03:36
| Again leave some space , open close bracket

|-
| 03:39
|Enter co-ordinates for point 1 (space) 0 (space) 0. Press enter

|-
| 03:45
|Now leave two '''vertical spaces''' , again press '''Enter''', again press '''Enter'''

|-
| 03:51
| leave some space and enter the '''co-ordinate '''for point number 4

|-
| 03:57
| Open, close bracket, enter '''0.707 (space) 0.707 (space) 0'''

|-
| 04:05
| Press '''Enter'''. Leave some space

|-
| 04:09
|Open, close bracket

|-
| 04:10
| Enter the co-ordinates for the point 5

|-
| 04:13
|Enter ''' 0.353 (space) 0.353 (space) 0''', press '''Enter'''

|-
|04:22
| Now leave 4 vertical spaces and enter co-ordinates for point number 9

|-
| 04:27
| '''1 2 3 4 ,''' again press '''Enter''', leave some space

|-
| 04:34
|Open, close bracket

|-
| 04:36
| Enter '''0 (space) 1 (space) 0''', press '''Enter'''

|-
| 04:42
| Leave some space

|-
| 04:44
|Enter '''co-ordinates''' for point number 10

|-
| 04:46
| Open close bracket ''' 0 (space) 0.5 (space) 0''' and press '''Enter'''

|-
| 04:54
| Similarly enter the co-ordinates for the remaining points in the geometry.

|-
| 05:00
|Insert a close bracket put a''' semi-colon''' and press '''Enter'''

|-
| 05:05
|Again press '''Enter'''

|-
| 05:06
| Now type '''blocks''', press '''enter'''

|-
| 05:13
|Insert a open bracket press '''enter'''

|-
| 05:16
| Let me switch back to the slides

|-
| 05:20
| The'''Block numbers''' are circled as shown in the figure

|-
|05:24
|Now let me switch back to the '''blockMeshDict file'''

|-
| 05:28
| Leave some space

|-
| 05:30
|Now enter the type of block i.e. '''Hex''' leave some space

|-
| 05:37
| Now enter the''' points''' for the '''blocks'''

|-
| 05:41
| Open, close brackets

|-
| 05:43
|Leave some space, the '''simple grading''' can be kept as '''(1 1 1) ''' and press enter

|-
| 05:55
| For creating the '''blocks''' please refer to the '''tutorial''' on '''creating simple geometry in OpenFOAM'''

|-
| 06:02
|Note that there will be more number of '''blocks''' in this example

|-
| 06:07
|Now insert a close bracket

|-
| 06:10
|Insert a semi-colon, and press '''Enter'''. Again press '''Enter'''

|-
| 06:16
| In the next line type '''edges''' and press '''Enter'''

|-
| 06:22
|insert a open bracket and press '''Enter'''

|-
| 06:26
| Here you need to enter the '''points''' which are the end points of the arcs

|-
| 06:31
|Leave some space and type '''arc''' leave some space type the points which are the end points of the arc

|-
| 06:40
|Let me switch back to the slide. Now insert the end points of the arc

|-
| 06:46
|In this figure, we start with arc '''0 5'''

|-
| 06:52
|Let me switch back to the '''blockMeshDict file'''

|-
| 06:56
|Enter ''' 0 space 5'''

|-
| 06:59
| Leave some space insert open, close bracket

|-
|07:04
| In the bracket enter the co-ordinate of any '''intermediate''' point in between the two '''arc points'''.

|-
| 07:11
|Now let me switch back again to slides

|-
| 07:14
| In the figure you can see that you have to pick up a point in between the two end points of the arc.

|-
| 07:23
|In this geometry I have picked up '''right half''' of the circle

|-
| 07:28
| Using '''simple geometric relations''' you can find the co-ordinates of the intermediate point as shown in the semi-circle

|-
| 07:38
| Similarly you can '''repeat''' the procedure for rest of the '''semi-circle geometry'''

|-
| 07:45
|Now let me switch back to the '''blockMeshDict file'''

|-
| 07:48
| press '''Enter'''

|-
| 07:50
| Note that there are more number of arcs in this example

|-
| 07:55
| Insert a close bracket

|-
| 07:58
|Insert a semi -colon press '''Enter''' again press '''Enter'''

|-
| 08:02
| Now enter the boundary patches after arcs

|-
| 08:06
|Refer to the tutorial on Simple geometry in '''OpenFOAM''', for entering the '''boundary patches'''

|-
| 08:12
| Enter '''boundary''',press '''Enter'''

|-
| 08:15
|Insert open bracket press '''Enter'''. Insert close bracket semi-colon, press '''Enter'''

|-
| 08:21
|Again press '''Enter'''

|-
| 08:24
| Now In the next line type '''mergePatchPairs'''

|-
| 08:29
|Note that '''P''' here is capital

|-
| 08:31
| Press '''Enter'''

|-
| 08:33
|Insert a open bracket, press '''Enter'''

|-
| 08:36
| Since there are '''no patches''' to be '''merged''' this can be kept empty

|-
| 08:40
|Insert a close bracket

|-
| 08:42
|Insert a '''semi -colon '''and press '''Enter'''

|-
| 08:46
|Let me switch back to the slides

|-
| 08:49
|Similarly enter the '''co-ordinate''' points for the points in the '''front face''' of unit thickness of the '''geometry''' as shown in the figure

|-
| 08:57
| Now open a '''Command terminal'''

|-
| 09:00
| In the '''command terminal''' type the path for your case

|-
| 09:04
| I have already set the path for the tutorial case of flow over cylinder

|-
| 09:10
| In the '''terminal''' type '''blockMesh '''for '''meshing''' the geometry and press '''enter'''

|-
| 09:18
|'''Meshing''' is done

|-
|09:20
|Now type '''paraFoam''' in the '''terminal''' and press '''enter''' to view the geometry

|-
|09:26
| Let me drag this to the capture area

|-
| 09:30
| Now on '''left-hand''' side of '''object inspector menu''' click '''Apply'''

|-
| 09:36
| '''geometry''' will be created as seen in the '''paraview window'''

|-
| 09:41
| Scroll down the '''Object inspector menu'''

|-
|09:44
| Check or uncheck the '''Mesh''' field box

|-
| 09:49
| You can see different regions of the geometry.

|-
| 09:53
|You can also see the''' wire frame '''of the geometry

|-
| 09:56
|On top of the '''active variable control menu''', in the drop down menu change from '''Surface''' to '''wireframe'''

|-
| 10:05
| You can see the '''wireframe model''' of the geometry

|-
| 10:11
|Close this. Let me switch back to the slides

|-
| 10:16
| In this tutorial we learnt:

|-
| 10:17
|How to create a curved geometry.

|-
| 10:20
