I have a converged car solution in FLUENT and I need to have a cut in the car and plot (pressure) in y-axis showing values of static pressure in the car in a side view (half) and the car in x-axis. How can I do that in FLUENT?

offffff, try to read and do the "tutorial 24 - Postprocessing" in Fluent Tutorial Guide, it will help you to get an idea about how to do it

man I understand that my question is too easy to you but for me I am a beginner and doesn't look that easy for me.

Anyway I look at tutorial 24 (FLUENT) its for Turbo post-processing its not what I need I just need the steps to do my question if you know.

Surface>iso-surface of constant grid at X=0m (or whatever) to create.
Then display contours on this created surface.

I have done your procedure but it seems that you didt understand me.
what i need is to take a cut from the car and display values of pressures instead of contour plots like XY plot with pressure.

yes but on what surface do you wish to plot? On an XY surface I assume (if no symmetry zone already) and this zone needs creating first.

I have a symmetry surface but i need the step or way to do it mate.

so you need to create line (or lines) for specific side position (surface> line) then go to XY plot to plot pressur vs (x or y) on the created line
you can plot pressur on created surface too but you will have n plots (n = nodes)

amazon thanks for your help indeed it was helpful.
However i tried it and i did had the results of the pressure distribution of the car using iso-surface but it doesnt recognize if upper stream or lower stream.
I think i have to use points or else to plot both upper and lower streams of the car in one XY plot.

ooh i think there is a misunderstanding when you said go to iso-surface did you mean in FLUENT solution or FLUENT results.
I would prefer using solutions

on the surface menu you could create line, rake, iso-surface to display or plot your results
on iso-surface you could create surfaces according to results values of any variable (such as max or min vorticity value or pressur or whatever)

euh ... i am confused ... but what s the diff between FLUENT solution and FLUENT results

Yes but if i have a car and i would like to chose the top part of the car only, which tool to chose?

thanks for the help i figured an easier way of doing it, i chosed points and then created them on the symmetry plane.
