Hi Bernhard,
I tried updating PyFoam to 0.5.1 so I can use it with OF v1.5.

Now I have the same problem as I had on the 8/11/07 above. The line you told me to change seems to already be changed in this new version. I added the line print mpirun and I get this error output:

user@linux:~/OpenFOAM/user-1.4.1/Trap> pyFoamPlotRunner.py --procnr=4 twoPhaseEulerFoam . cyclone1-newidea11

It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

Would appreciate any help.

Hi Jason!

No idea. Try running the command "by hand" (basically the above list with spaces instead of '.'). Adapt the command line until it runs. Then use the settings (http://openfoamwiki.net/index.php/Co...call_to_mpirun) to emulate the working command line for PyFoam

BTW: check with "which mpirun" which mpirun you're using

Hi everyone,

first of all: thank You Berhhard for pyFoam. I'm having some problems and haven't been able to make full use of it, but even pyFoamCloneCase and pyFoamClearCase, etc. make my life easier.

Ok, now to the problems:

my configuration:

HP Compaq 6820s Notebook PC - Business Notebook (Laptop) and Tablet PC
Chipset
Mobile Intel® GM965

OS
Ubuntu 8.10 Intrepid
FOAM

my problem:

I've installed pyFoam as non-root user, tried the test, and used scripts like the ones mentioned above. I want to use Runner utilities and control the runs with Networking utilities, but when I tried pyFoamRunner, here's what happened:

tomislav@icarus:run$ pyFoamRunner.py icoFoam ./ cavity
Error in /home/tomislav/OpenFOAM/PyFOAM/bin/pyFoamRunner.py : Case /home/tomislav/OpenFOAM/tomislav-1.5-dev/run does not have a 'system' directory

and within a directory,

What am I doing wrong?

Thank you,

[gschaider]

Hi Tomislav!

As you're using a 1.5-version (which has a new calling convention) you'll also have to use that convention for the pyFoamRunner-stuff. So

pyFoamRunner.py icoFoam -case cavity

or from within the directory

pyFoamRunner.py icoFoam

If you want to use the 1.4.1-version instead

pyFoamRunner.py --foam=1.4.1 icoFoam . cavity
or
pyFoamRunner.py --foam=1.4.1 icoFoam . .

lets you do this

Bernhard

[tomislav_maric]

Thanks, Bernhard. It works great now.

[jason]

Hi Bernhard,

The next time I come to use it it works fine with no errors? It works in both 1.4.1 and 1.5. Spooky.

for your info when running 1.4.1 'which mpirun' produced
/OpenFOAM/OpenFOAM-1.4.1/src/openmpi-1.2.3/platforms/linuxGccDPOpt/bin/mpirun
when running 1.5
/OpenFOAM/ThirdParty/openmpi-1.2.6/platforms/linuxGccDPOpt/bin/mpirun

Thanks Anyway

Jason

[jason]

Hi Bernhard,

Sorry I was being stupid. It still doesn't work.

However if I manually type the following
mpirun --mca pls_rsh_agent rsh -np 4 -x PATH -x LD_LIBRARY_PATH -x WM_PROJECT_DIR /home/user/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/twoPhaseEulerFoa m -parallel

I get the error from 05/03/09

I dont really know what I am doing but if I type

mpirun --mca pls_ssh_agent ssh -np 4 -x PATH -x LD_LIBRARY_PATH -x WM_PROJECT_DIR /home/user/OpenFOAM/OpenFOAM-1.5/applications/bin/linuxGccDPOpt/twoPhaseEulerFoa m -parallel

ie change rsh to ssh then the calculations progress but I dont see any graphs.

Do i need to make this change somewhere? If so where?

Thanks

Jason

[gschaider]

Hi Jason!

"Don't see graphs": You mean "Because it is not run in the PlotRunner"

To make this permanent change the "_pre" variable as described in:
http://openfoamwiki.net/index.php/Co...call_to_mpirun

BTW: Just as your message arrived I finalized a new release of pyFoam. It doesn't directly address your problem but it has an additional switch in pyfoamrc

[Debug]
parallelExectuion = True

that outputs which call to mpirun PyFoam uses.
Other features of the new release (among this better suppor for paraview) are listed in http://openfoamwiki.net/index.php/Co...PyFoam#History

Hi,

I must need glasses, to me its not clear on the wiki which file to change so I changed this one in my source code.

~/PyFoam/PyFoam-0.5.1/PyFoam/Infrastructure/Configuration.py

and then reinstalled and now everything works.

Thanks

Jason

[gschaider]

Hi Jason!

As described in the section above: either /etc/pyfoamrc (for system-wide changes) or ~/.pyFoam/pyfoamrc (just for you). You'll propably have to create these files

Changing the source-code is an alternative but will break your setup with the next update

Bernhard

[jason]

Thanks Bernhard,

I got confused because I couldn't find the files and didn't think of creating them myself.

Everything is working fine now.

Regards

Jason

Hi all!

Would you please help, how to tell pyFoamPlotWatcher to plot data for each ITERATION rather than for each TIMESTEP? I use customRegexp to plot data I need, but still graphics output is produced for each time step depended on deltaT, ignoring all other lines which meet regex.

Thank you!

[makaveli_lcf]

There is a line:

LogAnalysis/TimeLineAnalyzer.py: timeRegExp="^Time = (.+)$"

which controls watcher objects time triggers. So there 2 possible solutions for my task (excepting modification of timeRegExp variable):

1. Print "Time = iteration_number" after each iteration to use logfile from standard out to plot residual with pyFoamPlotWatcher. But then time-step information is messed with iterations output.
   
2. So I preffer to print iteration residuals to other output stream/log file inside solver to display internal loop convergence separately with pyFoam switching off all other plots.

Perhaps there ara some better solutions, but this one do not require much modification to python scripts or solver source code.

Hi Alexander!

One of the reasons that only the accumulated value for the iterations is plotted is that to me it seemed to be the most general measure BUT the value for single iterations is already there. In the *.analyzed directory (use --write with the watcher, the Runner should create this files automatically) you will find for instance files linear_p (with the values of the first iteration in each timestep), linear_p_2 (with the values of the second iteration) and so on. So if you want to plot the number of iterations for each solution of p use these and Gnuplot (or the plotting program of your choice). This is more or less what you

If you want to do it online these lines in customRegexp might for instance plot the number of iterations the first and the last solution of p in a timestep need. And how often p is solved (if this is variable in you algorithm)

{"expr":".+  Solving for p, Initial residual .+ No Iterations (%f%)","name":"Last iteration","accumulation":"last"}
{"expr":".+  Solving for p, Initial residual .+ No Iterations (%f%)","name":"First iteration","accumulation":"first"}
{"expr":".+  Solving for p, Initial residual .+ No Iterations (%f%)","name":"Nr of iterations","accumulation":"count"}

This is only possible using the customRegexp-file not from the command line

I don't want to introduce the notion of internal-loops to the time-counting mechanism, because as you noted in point 1 there is not good way to plot both (unless you want to crowd the linear graphs with p, p_1 to p_42)

Greetings!
Fabian

Hi Fabian,

I still feel that I am new to this field, what would you do after turbFoam? If you take the sequence of potentialFoam / simpleFoam / turbFoam / oodles.

you see in oodles you have to give the i.c. and b.c. in the beginning, but what's your custom to get these values from tubFoam, they are different after all. (eg. how could you get nuSgs nuTilda from nut k ...? )

Am I missing some secrets that you all know? Thanks

Hello World.

I'm not sure what went wrong, I followed the instruction to install as root.
This is what I get, when trying to test the installation:

Yeah. You mistyped. On http://openfoamwiki.net/index.php/Co...e_installation
it says FoamInformation NOT FoamInstallation. What I usually recommend is copy/pasting that kind of stuff from the Browser to the Terminal

Hi all together,

I am using pyFoam and never had problems untill now. But after updating ubuntu to Version 9.04, everytime I want to start a calculation, I get the following message:

"
/usr/local/lib/python2.6/dist-packages/PyFoam/FoamInformation.py:5: DeprecationWarning: The popen2 module is deprecated. Use the subprocess module.
from popen2 import popen4

At the beginning of the thread, I wrote about about a mistake with the pythonpath, but I don't know, how to deal with it. I tried to install pyFoam completely new (as root using "sudo") but after installation, I see the same message again!

Thanks for reading

Some more information,
when I try to install PyFoam as root (using "sudo"), I get two errors. But the the installation runs further.

The errors:
