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!

Hi,
I just tested it from the console with

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

I get as error message:
'/home/fab/OpenFOAM/OpenFOAM-1.1/bin/paraFoam: line 57: 7023 Segmentation fault paraview paraFoam.pvs'


Does anybody understand this?

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.

Hi,

thanks for the suggestions, unfortunately it does not help...
I checked paraview on his own, which works fine, got rid of the trailing '/' and deleted old paraview files. Strange!

Your probably have NaN-s or similar garbage in one of your result files. I have seen this before.

Hi all,

Does anybody know if it is possible to mirror the geometry in Paraview; if yes, how?

Thanks

(have never tried it though)

Or use OpenFOAM utility mirrorMesh to build a symmetric mesh (not sure if it does fields as well)

Hi All,

I have been trying to do the lid-driven cavity flow tutorial.Post-processing with paraFoam shows the following error:

...in this the ParaFoam window shuts down as soon as it opens up!
Although there is no such problem with paraview
which i had separately installed after downloading it from paraview.org.

Any ideas???can this problem be sorted out by some means...Do i install OpenFoam to the system again?

Cheers
Kanishka

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.
I intend to convert my simulation data into VTK format with "foamToVTK", put it on my windows machine and doing the visualization.
Will it be identical to calling "paraFoam" with the corresponding case?

Hi Henry,

Please tell me how to install ParaView-1.8.5 over ParaView-2.0.2.I am struggling with 'rpm -e' command to do so,not having much knowledge of commandline interface.How to use 'foamToVTK' converter?

And how to do post-processing with dxFoam.
'dxFoam postFoam' shows the following message:
Executing: /home/kanishka/OpenFOAM/OpenFOAM-1.1/.bashrc
Executing: /home/kanishka/OpenFOAM/OpenFOAM-1.1/.OpenFOAM-1.1/apps/dxFoam/bashrcExecuting: /home/kanishka/OpenFOAM/OpenFOAM-1.1/.OpenFOAM-1.1/apps/ensightFoam/bashrc

[kanishka@fedora1 ~]$ dxFoam postFoam
Checking path to dx ...
Checking path to dxFoamExec executable ...
Can't find dxFoamExec executable. Please check your path.

I have downloaded the installer files of OpenDX from http://www.opendx.org/dlBinary.php
While installing it shows:
[kanishka@fedora1 ~]$ rpm -Uvh opendx-4.3.2-1.rh9.rpm
error: can't create transaction lock

how to install and work with it??
..please suggest something.

Kanishka

To install ParaView-1.8.5 available from the OpenFOAM download site follow the instructions supplied.

Use foamToVTK in the same manner as all the other OpenFOAM utilities. Usage is described in the documentation.

dxFoam is no longer supported.

Bug in tutorial setup, maybe also in FoamX config, but I'm not checking. Edit the file:

OpenFOAM-1.2/tutorials/buoyantFoam/hotRoom/0/p and for all patches of type wallBuoyantPressure add the "default" value for post-processing, e.g.:

floor
{
type wallBuoyantPressure;
value uniform 100000;
}
