Hello all,

I want to compare experimental data with my results from the simulation using gnuplot.
Because my simulation is about a turbulent jet-flame, I want to plot for example the velocity or temperature over a radial profile.

It should looks like that:

It would be very helpful, if somebody could give me a step-by-step solution, how something like that is done.

I'm thankful for every advice.

kind regards.

there is a tool called sample, which you should use to get xy plot of your data.
you need a sampleDict, which you can find in the openFoam source. All is explained inside this dict.
After that, you can create gnuplot dict to plot the data located in .xy file you created with sample. http://www.gnuplotting.org/plotting-data/
