Dear Mates,

Thanks to Far, I just found a way to plot average values like pressure in Fluent. For example you want to plot average pressure along a pipe. In TUI, under Plot, there are two options:
1-circum-ave-axial
2-circum-ave-radial
First you should find which direction suits you. you can figure it out by computing grid scale under Surface-->Iso-surface by selecting Grid and then Axial Coordinate or Radial Coordinate as the options.
Then using above-mentioned commands you can simply export averaged values to an excel or whatever format.
Remember to select the Fluid ID as the target surface when Fluent asks you!

I hope this can help!
