Hi FOAMers.

I'm trying to manipulate OpenFOAM in iPython (jupyter notebook).
I want to get like a plot data generated by pyFoamPlotWatcher.py in line as following.

[In]
Code:
import os
import shutil
from PyFoam.RunDictionary.ParsedParameterFile import ParsedParameterFile
from PyFoam.Execution.BasicRunner import BasicRunner
from PyFoam.Execution.GnuplotRunner import GnuplotRunner

from PyFoam.IPythonHelpers.Case import Case

orgCase = os.path.join(os.environ['FOAM_TUTORIALS'],'incompressible','simpleFoam','pitzDaily')
newCase = os.path.join('./result/pitzDaily_')
shutil.copytree(orgCase, newCase)

blockMesh = BasicRunner(['blockMesh','-case',newCase], silent=True).start()
simpleFoam = GnuplotRunner(['simpleFoam','-case',newCase], progress=True).start()

case = Case(newCase)
plots = case.pickledPlots(case.sol.pickledPlots[0])
plots['linear'].head()
[out]
Code:

5.0           4.0  0.117570  0.011387           3.0
then, I could get dataFrames like pandas' .

BUT a gnuplot window always did popup and I don't need it because I want to do case study and to compare the plots of the each cases.

Do you have any ideas to avoid the pop-up window of gnu plot or to analyze logs silent ?

Best regards.

Solved as following.

Code:
simpleFoam = GnuplotRunner(['simpleFoam','-case',newCase],progress=True,gnuplotTerminal='/dev/null').start()
Thanks
