Hi guys, I am facing troubles plotting the forces with pyFoamPlotRunner.py. I don't know what to write in the customRegexp to extrapolate the values that I need. Here is the output from the log:

forces forces write:
sum of forces:
pressure : (676.417 0 5.76293e-14)
viscous : (0.0234939 0 5.45593e-18)
porous : (0 0 0)

The best would be to plot the sum of x pressure and x viscous and so on.
Thank you in advance!

Simply built a small bash script that executes gnuplot (or a gnuplot script) which uses the data given in postProcessing/<youFOName>/... Here you have the output already as you want and the script will re-read, e.g., each second or if the file was modified.

5 - 10 Min work.

The fact is that I am running the pyFoamPlotRunner.py inside a bash file because I want to automatize all the processing of running a simulation, so unfortunately I do not know if this option is feasible to me. Anyway I will try, thank you

Of course, you can put a gnuplot command into a bash-shell script. Even if you push it to the background.
