Interesting but not in release notes: 1.3 foamToVTK runs in parallel. Produces one VTK directory per processor. Has got some new useful command line options as well (e.g. -allPatches)

[cauneau]

Using release 1.3: test on launching paraview-2.4.2 from inside FoamX (testcase is tutorial icoFoam/cavity). Everything fine, except on calculating streamlines. Error Message is:

ErrorMessage
# Error or warning: There was a VTK Error in file: ../../../../../paraview-2.4.2/VTK/Filtering/vtkDemandDrivenPipeline.cxx (661)
vtkCompositeDataPipeline (0x92c4200): Input port 0 of algorithm vtkDistributedStreamTracer(0x92c5be8) has 4 connections but is not repeatable.
ErrorMessage end

Other glyphs and 3D objects display quite normally...

I shall try to hack a little to know more.

NB1: Host system is a linux-mandriva (kernel 2.6.12), running on a laptop dell latitude (i586).

NB2: For the X server, "DRI" is off, as it is not compatible vith some calls of the PatchTool interface. Switching it on doesn't fix the present VTK problem.

NB3: Everything works fine with the couple OpenFOAM-1.2/paraview-2.2.0 on the same machine.

Hello Foam Guys

I experiment the same troubles that Francois Cauneau, both in my house machine (amd 32 bits) as well in my job (amd 64) using openfoam 1.3 + paraview 2.4.2.

Somebody can help us?

Many tanks in advance

the following is the error message i get when i try to open paraview. My aim is to plot stream lines for backward facing step flow. can some one tell how to do that with lines/points/ribbons instead of tubes.

also i need help regarding this error. i tried reinstalling but still ended up with same error. so, plzzzzz help me as soon as u can

Hello,
I tried the conjugateFoam7 solver and it went well after I got the help from you to compile the source. Now I want to see the results.
Having multiple regions seems to enforce the usage of foamToVTK.
Well, I tried it, and I can see the temperature field for instance, but no velocity. It is obvious that when I ran it, the program complains about something:

Use the search facility. Look for CyclicPointPatchField.

[dmoroian]

Hi Mattijs,
The solution worked immediately. Thanks!

By the way, I always search first the forum, before I add my question. My fault is that I searched for the wrong key ("foamToVTK" instead for the actual error).

Regards,
Dragos

Hi,
I was wondering if anyone could give me a pointer on what a foamToVTK error message means. I am running twoLiquidMixingFoam without any problems in the simulation, but when I run foamToVTK it spits out.

--> FOAM FATAL IO ERROR : size 6000 is not equal to the given value of 10400

FOAM exiting

I looked at the data file and their are 6000 data points for gamma but I don't know where this other number 10400 is defined. I am a little bit of a newbie still, so I have to apologize for my lack of error message knowledge.

Shawn

[hjasak]

Take a look at the file:

0.01/gamma_0

and swee what the field size is. It should be the same as the number of cells in the mesh. If it is not, delete it. Do that with all other fields if the error appears again.

You can find the number of cells in the comment (under nCells) in constant/polyMesh/owner

Enjoy,

Hrv

What kind of error is this??

I have solved this irritating problem before. Here you go -> http://www.cfd-online.com/OpenFOAM_D...es/1/4438.html

Thank you.
I'll check it.

Dear All

would you please any one let me know, which kind of problem has my paravies which shows the following error?
and what should i do with that?
i use OpenFoam 1.4 , with paraview 2.4.4.

# Error or warning: There was a VTK Error in file: /home/dm2/henry/OpenFOAM/linuxSrc/paraview-2.4.4/VTK/Filtering/vtkDemandDrivenPi peline.cxx (651)

hi everyone,

i need to generate a mesh around a cylnder. i have started with quarter of it. now how to complete it? i tried with filter>Reflection in paraview. it was working but i have a doubt that paraview being just a viewing tool, if i take the reflection, is it really going to change my computational domain physically??

this is a kind of urgent. reply will be greatly appreciated.

regards,
nike

[ngj]

You just need to do what you have done already three more times to end the circle, i.e. you have to generate the mesh around the entire cylinder using whatever meshing-tool you are comfortable with.

ParaView is "merely" a postprocessing tool.

/ Niels

[nikhilmadduri]

thanq Niels,

I am able to do it by inputting all the other 3 parts too again and was able to generate the whole cylinder using blockmesh. but since rest 3 parts are just symmetric along either x or z axes, do i have any tool which can just take the mirror image such that my tedious job of inputting all again will be reduced?

regards,
nike.

hi Henry,

I was reading your post above and would like to ask you regarding a problem of pre-installed paraveiw.

I am unable to execute the command paraFoam correctly. i get the following error

mayank-guptas-macbook:icoFoam mayankgupta$ paraFoam ~/openfoam/mayankgupta-1.4.1/run/icoFoam cavity
/Users/mayankgupta/OpenFOAM/OpenFOAM-1.4.1/bin/paraFoam: line 75: paraview: command not found


can u help me fix this problem. I have installed paraview as a disk image and i am completely new to linux and no nothing about computers. secondy i was trying ur solutions of setting the environment for paraview but i could not find the paraview directory in the applications directory of openfoam-1.4.1

please help.

thanx

Dear All:

The following options are given for suitable Qt for different versions of SuSE:

The default versions of Qt used by some GNU/Linux releases are as follows.

* ubuntu-7.10: Version 4.3.2
* ubuntu-8.04: Version 4.3.4
* openSuSE-10.2: Version 4.2.1 - too old
* openSuSE-10.3: Version 4.3.1
* openSuSE-11.0: Version 4.4.0 - too new

I am running SuSE 10.0 Does this mean I will need to upgrade to 10.3, or is there something availabe for 10.0
Thanks
Musa

Dear All:

just managed to start paraView for OF1.5. It looks wonderful! However: it seems like running a case does not produce any files for paraView to read, that is, I can see the mesh doing the cavity tutorial. But there is no way I can get any additional info after running icoFoam. The same goes for the damBreak after running interFoam (looks ok while running). What could be wrong? My OS is Ubuntu 8.04.
Thanx,
Annika
