When I run a case normally it runs fine.

However when I run it as pyFoamPlotRunner.py simpleFoam, it seems to run fine and creates a bunch of pyFoam files and directories in the case directory, but does not plot any of the required residuals. Gnuplot does not even open.

I am not getting any errors and do have gnuplot installed.

Any suggestions?

Thanks in advance.

Look at the date of your posting: Gnuplot refuses to work on Sundays. PyFoam works on sundays but respects the right of Gnuplot to have a day off.

No seriously. I guess you did your research and it is not the well known "I work with Ubunutu where there is a gnuplot and a gnuplot-x11-package. The first is installed by default the second one is the one I want because it draws windows"-problem. Please check whether Gnuplot draws windows if used by itself. If that works (and only then) the problem is PyFoam. Is there ANY output in the beginning that could give a hint about the problem

As explained by gschaider, you should be seeing an error at the start, which says something about "X11:missing"

To solve this run:

sudo apt-get install gnuplot-x11

After that you can run:

pyFoamPlotRunner simpleFoam

And it should work, although I would recommend you using

pyFoamRunner.py --progress simpleFoam

And after that run

pyFoamPlotWatcher.py --silent PyFoamRunner.simpleFoam.logfile --hardcopy

Which should give you nicer plots, and will have better performance in your simulation.

I agree it was unfair of me to ask gnuplot to work on a Sunday (-:

Thank you both sssss and gschaider for helping a newbie out. Success!

Another question on pyFoam,

how does the ClearCase command work?

When I run pyFoamClearCase.py in the case directory it gives an error and says I have to specify a parameter, what parameter is this?

Also, on another subject, might one of you be able to help me with these questions:

The directory you want to clear. In your case a simple . will be sufficient.

It HAS been asked in the past whether I could make this utility run parameter-less, but I'm a strong believer in the second Zen of Python ("Explicit is better than implicit". See http://legacy.python.org/dev/peps/pep-0020/)

Due to time constraints I limit my answering to some topics (PyFoam is one of them, but these are not)

[mich_K]

Understandable.

Thanks Bernhard!

Hello.
I have similar problem as mich_K. It is sunday and pyFoam does not want to plot.
I have installed pyFoam and gnuplot as "notroot" user to my home directory.
gnuplot works fine - after command "plot sin(x)" window appears.

But if I run pyFoamPlotRunner

]$ pyFoamPlotRunner.py potentialFoam
