Hello Foamers,

I have successfully used pyFoam in the past to plot residuals during runs, but now that I have upgraded to OF2.4.x there seems to be a compatibility issue. PyFoam just hangs at the first timestep. Running the case without pyFoam does not produce the error, so I don't think it has to do with my /system/ files, but I have attached them nonetheless. The command I am running is:

Code:
decomposePar -force -cellDist
mpiexec -np 4 renumberMesh -overwrite -parallel
pyFoamPlotRunner.py mpiexec -np 4 simpleFoam -parallel
And the resulting error message is:

Code:

Howdy Foamers,

I have not been able to solve my problem yet, but I did some further reading and came to two possible sources of error.

-- First off, it looks like I had not installed PyFoam since I switch from python 2 to python 3. Oops.
-- Second, I was not correctly operating PyFoam in parallel correctly. I should have actually used the command

Code:
pyFoamPlotRunner.py --procnr=4 simpleFoam
Changing these two options made it so the tutorial cases run correctly, but my case is still not able to start. Would anyone be able to help me with my persistent problem regarding PyFoam?

Hey foamers,

I just finished the installation of PyFoam and unfortunately have equivalent problems when running the PyFoamRunner.
I am doing a single core simulation of OFs damBreak tutorial. OF writes the first two time directories and stucks shortly after this.

My PyFoamRunner.py output following:
Code:

Checking additional envirnoment variables

Checking for PYFOAM_DIR : Location of the PyFoam-installation. Not strictly necessary
PYFOAM_DIR missing from environment

Checking for PYFOAM_SITE_DIR : Location of non-PyFoam-disctributions script. Set and used by some Foam-distributions
PYFOAM_SITE_DIR missing from environment
Has anyone experienced anything similar or an idea on how to get the PyFoamRunner running successful ?

Checking additional envirnoment variables

Checking for PYFOAM_DIR : Location of the PyFoam-installation. Not strictly necessary
PYFOAM_DIR missing from environment

Checking for PYFOAM_SITE_DIR : Location of non-PyFoam-disctributions script. Set and used by some Foam-distributions
PYFOAM_SITE_DIR missing from environment
Has anyone experienced anything similar or an idea on how to get the PyFoamRunner running successful ?
Hm. That is a strange one. The problem seems to be that the file ./PyFoamRunner.interFoam.analyzed/pickledPlots.tmp can not be removed because some other process is accessing it. Is the file there? Could you try "lsof ./PyFoamRunner.interFoam.analyzed/pickledPlots.tmp" and see if it gives any output? (If it doesn't then this unfortunately no proof that there was no other process at the time of moving). The file is released immediately before moving it. It COULD be a race condition in the operating system and that is hard to fix

Hello Mr. Gschaider,

thank you for your hint. I executed the lsof command as you suggested. The output shows that the file is in use during runtime (by my own user to be precise).

I use OpenFOAM in a virtual machine which contains some shared folders to make the simulation and result files available on other machines during runtime. I assume that these shared folders are monitored the whole time to provide a rapid availability on all systems which seems to be the main problem.

When I move the case directory to a local folder (not shared) and start the simulation there are no more errors and the pyFoamRunner works properly !

Iam looking forward to explore your tools.
