I've already finished my simulation. Next is to analyse my result, I want to look at the pressure drop so average pressure is require. How can I get it from CFD post?
I tried to read from the user guide but couldn't find.

Thankyou

Try to plot Cp over the geometry,so with the definition of Cp you will be able to calculate pressure drop.

Thank you very Much, Could you please explain to me briefly? I don't know how to make a plot. Sorry I'm newbie in CFD

You need a plane where you want to average pressure. If you don't have one already you have to make one using Location -> Plane.

Then you can use Function Calculator to ave the pressure at the plane.

Pressure difference in two different location, obviously, is a pressure lost.

By the way, you can do a similar thing inside Fluent as well.

Ok, after your results converges,then stop running the program, in plot tab go to XY plot icon then choose Pressure... item from the scroll bar upper right the window and below that choose pressure coefficient, also u should click the surface that you want the value of pressure drop on that,then simply click on plot icon.
Cp=(P-P(infinity))/(0.5*density*V(infinity)^2);
in your problem u have every thing except (P) so P-P(infinity) is pressure drop.
good luck.
