Temperature and streamlines simultaneously in paraview for wedge-typed mesh
1 Attachment(s)
Greetings All
I want to get a picture from paraview which has both temperature contour and streamlines. After clicking on stream tracer from filter in paraview, I need to specify points for line source; I do not know how to determine these points for a wedge-typed mesh. would some body plz hint me? My system of coordinates are completely clear from the attachments; If you tell me where the point should be, I would become very happy. X domain: 0 - 0.15 y domain: 0 - 0.9 z domain: -0.0065429081 - 0.0065429081 Regards Bobi |

I found the point source positions: (according to geometry) (0 0.45 0) to (0.15 0.45 0) The result is the following image; however I want a continous temp slice on which streamlines are shown in black lines. would somebody plz hint me how can I get it? Also in Sources->Ruler; when we use this ruler nothing happens in the pic; how can we have a real ruler that shows distance in any location of the pic? Any hint? Regards Bobi |

Greeting all
I have posted the best pic I got from paraview and the shape that is my desired. Would anybody PLZ hint me how can I get the desired pic (left one) from paraview? Kind Regards Bobi |
Hi Bobi,
you want the left picture visualized in paraview? Can you sent me the case (last timestep) without PDF on my email account. Then I will have a look on it. Regards Tobi |
Hi Tobi
Yes, What I got as the best is the right picture; however I want sth like the left one i.e continous temperature profile with streamlines in black on it. I sent the requirements via file2send. Kind Regards Bobi |

Hi Bobi,
is this related to that you want? Regards Tobi |
Hi Tobi
Yes, Exactly sth like this. Would you PLZ hint me how did you do this in paraview? I can cut a slice through the mesh and get the temperature distribution on it;but how about black streamlines? What I found in paraview is colour lines (from stream tracer) not these black lines that you put on the image. The advantage of black lines is that it makes stream lines distinctive from the background temperature. Another important question. Is there any way to put vertical and horizontal rulers around our graph (like tecplot) in paraview? Kind Regards Bobi |
Hi,
hmmm ... i dont know if this is possible or how to do that. In the attachment you find a file you can load with paraview. 1. cut your domain with some clips 2. build a slice through your domain 3. add calculator 4. build new vectorfield "Velocity_xy = i_Hat*U_X+j_Hat*U_Y" 5. streamlines with that source on a line 6. move your slice to temperature values 7. move your streamlines to "solid color" 8. change color to black and maybe print your lines thicker 9. build glyph on streamlines with the velocity field 10. change type to "cone" 11. change settings of cone 12. enjoy. Regards Tobi |
Hi Tobi
Many thanks for your instructions. Also I tried to open the file you had put in the forum with paraview. I put it on its original folder. After running paraview from that folder and loading state (this file), I confronted with this error: Code:
babak@babak-System:~$ cd OpenFOAM/babak-2.2.x/flameletModel-2.2.x/tutorials/flameletSimpleFoam/HM1Tobi2 Also if the data can be used by others, I would be glad if you delete the file,cause I have downloaded it. Regards Bobi |
Hi Bobi,
well it seems that PV Need my Folder: Code:
Can't open directory /home/shorty/OpenFOAM/shorty-2.2.x/run/case/ Regards Tobi |
Hi Tobi
From your instructions I learned new things in paraview:) :D Many thanks. Just two short questions: 1- Your streamlines have orientation, but mine didn't get. would you plz allude to the place where we put orientation on our streamlines? 2- what is the role of glyph? with slice - calculator and stream tracer consecutively, I got sth like your image. The same pic achieved by glyph, though. Kind Regards Bobi |
Hi Bobi,
my streamlines have no orientation. On the streamlines I used the filter "glyphs" to get the orientation shown as small triangls :) that s all. In that filter you have to use the befor calculated velocity field (source). Then you will have 3D glyps with orientation. Then change 3D Glyphs to the settings you want to have. Additionally change the parameters so that your solution is good for you. Regards Tobi |

Hi Tobi
I took a look into paraview tutorial too. I got what is going on with Glyph filter. I tried a lot to got a nice pic, however it seems that glyph settings is not that much simple.:( I took a snapshot from my paraview that shows my glyph settings. I would be very glad if you put a snapshot like mine that shows your glyph settings. I don't know where is the problem because pointers about the bluff body are very big, but in the bluff-body wake they are small. Regards Bobi |
Hi,
you are not doing that: 1. cut your domain with some clips - cut the domain into the interessting domain 2. go down the properties menue and set scaling to "off" 3. set a good scale factor your self 4. decrease the number of glyphs Have fun, Regards Tobi |

Hi Tobi
Many thanks for your helps. Finally I got a nice pic. Although the density of streamlines around the vortices center are high but generally the quality is acceptable. @ Bruno Hi buddy Would PLZ take a look at my pic and the desired one? I need to put a coordinate system with the origin at the leftmost point in the inner jet exit. (sth like the desired pic). Does paraview support this capability? Kind Regards Bobi |
Greetings to all!
@Bobi: If the results are in 3D, then the only thing I know of is the Cube Axes: http://www.paraview.org/Wiki/ParaVie...tion#Cube_Axes Best regards, Bruno |
Hi Bruno
Many thanks for your help. Wedge-typed mesh is kind of 3-D. I am going to take a look into the link. Regards Bobi |
Hi Bruno
Just a simple problem. Where is this filter i.e. cube axes? I can't find it. Regards Bobi |

Dear Bruno
Many thanks for your kind hints. I am using paraview 3.12 with O.F. 2.2.x. It seems that I should upgrade my paraview version to 3.14. would you PLZ hint me how can I do this without affecting my O.F. settings? I mean without leaving O.F. 2.2.x. Regards Bobi |
Hi bobi,
download the binaries of the latest version, unzip it and run it :) |
Hi Tobi
I am trying to download paraview 3.14 or 3.98 from http://http://www.paraview.org/parav...s/software.php However after downloading 30% of it. then suddenly it crashes. Mt internet speed is 1 Mb/S. I don't think that it is from my internet speed. Is there any way to get paraview 3.14.1 or 3.98 from terminal of ubuntu(12.10) ? I have looked into openfoam.org site; maybe this directive: Code:
sudo apt-get install paraviewopenfoam3141 Regards Bobi |

I didn't say you needed to upgrade, I only said that it depends on which version you're using! The first picture shows where the controls are in ParaView 3.12.0 and the second one on ParaView 4.0.1. Now do you understand what I meant? ;) Best regards, Bruno |
Dear Bruno
Many thanks. The thing that made me confused was a sentence in your second link that says that some options has been added after 3.14 version. Cause I didn't find cube axes, maybe I thought its because of my version. So many thanks of both of you (Bruno and Tobi) Kind Regards Bobi |

Dear Bruno
I learned how to work with cube axes from your links. I took a pic from my result. Although I put coordinate system on the place that I want, but there are still two more necessary modifications. First of all, I need to non-dimensionalize my axes by 0.025 factor. Secondly, I need to start my Y-axis from the 0.1 point i.e. change 0.1 to 0 . I think my problem is a need to define a kind of arbitrary axis. PHP Code:

Any hint is appreciated.:) Kind Regards Bobi |
Hi Bobi,
You'll have to think the other way around: don't think about changing the "cube axes" representation; think about transforming your geometry into the the shape you need it to be. For that, use the "Transform" filter. Best regards, Bruno |
Hi Bruno
You're the best:):D:D:) Exactly I got what should I do. I hope that my questions and your unique answers would help other people confronting same problems. However I should mention that 2 consecutive transfrom filter is needed one for translate and the other for scale. I don't know that why it wasn't applicable with one transform filter. Long live Bruno. Regards Bobi |
Hi Bobi,
2 transformations? That's normal. And consider yourself lucky you didn't need 3 or 4. This is due to how ParaView provides the transformation filter, since it doesn't expose the final transformation matrix, which would enable us to just do a single transformation. Best regards, Bruno |
