[PyFoam] Using pyFoamPlotWatcher.py To Plot Residuals

OlivierM · January 26, 2021, 05:01

Many thanks Bernhard !
I was unable to remove all these files but uninstalling/resinstalling pyFoam was enough to take this step.

Now I have a new problem which seems about gnuplot:

Code:

$ pyFoamPlotRunner.py simpleFoam
PyFoam WARNING on line 37 of file /usr/local/lib/python3.8/dist-packages/PyFoam-2020.5-py3.8.egg/PyFoam/Infrastructure/ServerBase.py : No certficate file (...) no SSL-connection (...)

gnuplot: unable to open display ':0'
gnuplot: X11 aborted.

gnuplot-x11 is installed
Terminal type is 'wxt'

do you have any idea about what could be wrong ?

X11 is a server-client protocol. The program is the client. It needs a program that does the actual drawing: the X11-server (on Unix this is running on every machine that has a GUI because it draws the GUI). Seems that such a program is not running on your machine
Don't know what is the recommended X-server on windows nowadays

Xming still does the job for me with v2006 but I would be interested to know if there are better X-servers out there.

Best,
Petros
