Hi,

I am not able to take a look at the results and grid with paraview/paraFoam anymore. It worked before and I don't know what I changed.
If I choose the 'normal' way by the utilities-menu to postprocess the data with parafoam, paraview opens up normal, but pressing the 'accept' button it seems that paraview wants to load the data and closes the environment afterwards. OpenFoam than tells me that the 'Application parafoam (pid ...) did finish successfully', but I don't want to finish it before I can see anything...

Does anybody have an idea what went wrong?

Greetings!

Well, reading the error message tells me:

Segmentation fault paraview

0) try running paraview on its own (this will check the installation

1) get rid of the trailing "/" in the root entry on the command line:

'paraFoam OpenFOAM/fab-1.1/run/tutorials/buoyantFoam hotRoom'

2) Try deleting all old paraview files in the case directory and try again.

The PVFoamReader is compiled for ParaView-1.8.5 not for ParaView-2.0.2. Your options are:

1) install the ParaView-1.8.5 we supply with OpenFOAM-1.1

2) recompile PVFoamReader for ParaView-2.0.2 (but it probably won't work due to changes in ParaView)

3) use the foamToVTK converter and run paraview rather than paraFoam.

Hi,
I want to do parts of my postprocessing on a windows machine. I installed a binary version of "paraview" there.

Will it be identical to calling "paraFoam" with the corresponding case?

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.

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

Take a look at the file: 0.
 

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

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

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.

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?

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.
