im simulating a combustion in a cylindrical combustion chamber. I want to plot the heat release rate integrated over the volume along the flow axis. The goal visuals the heat release rate of the fluid domain as a function of the flow axis (distance).
Does anyone have an idea?

In Fluent you can plot temperature, and there are other options once you turn on the combustion model(s). Look for the Plots (commonly called xy plots) in the Results section.

Hey Rob i know these options. But for my problem i think i have to create a user defined function. i try to plot a graph that shows the sum of the integrated heat release rate (thermal power) on the whole surface in the cylinder in function of z (flow direction).
Do you understand what i mean?

technically i need an infinite amount uf surfaces along the cylinder to read the data, but doing that manually would be insane, so i was thinking if there might be some routine for that.

Pictures will help. If you want position & flow data on the casing have a look at profiles and/or Export options. UDFs are more advanced and often used where some creative use of user surfaces is sufficient.

And you want the integral (or whatever) at intervals along the casing? You may need to use the TUI to build a journal to create the faces (edges) on the casing. The rest is from the Surface integral tools.
