Hi everyone,
when I want to run my case in 2.4.0 version of OF by this command as I had done before in 2.2.2 version
Code:
pyFoamPlotRunner.py --hardcopy --with-deltat --with-courant --procnr=4 rhoCentralFoamGasCont
this warning is shown and although it runs successfully but doesn't plot residuals as before
Code:
 PyFoam WARNING on line 142 of file /usr/local/lib/python2.7/dist-packages/PyFoam-0.6.4-py2.7.egg/PyFoam/LogAnalysis/GeneralLineAnalyzer.py : Problem doing timelines could not convert string to float:  
Time = 1.8007576e-05
what could be the reason?
thanks a lot.

that error has resolved,now another error on gnuplot is shown, the graphs are written to disc but don't show while running the case.
Code:

Hi,

I also get a similar error on Ubuntu 14.04.2 and OpenFOAM 2.4.0, if I type gnuplot and then set terminal the x11 type is not listed

Any luck finding what's wrong? Maybe I will try an earlier version of gnuplot.

Ok, so if you install gnuplot and then install gnuplot-x11 it then works ok. gnuplot-x11 is the driver to plot to the terminal and its not included in the main gnuplot package.
Doh.
