I need URGENT help for following problem related to output from FLUENT.

I have a two quantity relative pressure and velocity magnitude distribution in computational domain. I have plotted a graph or output for the absolute pressure and velocity with respect to x-axis or longitudinal axis of domain.

Now I want output as power which is defined in my case as:

Power=0.5* P * U * c/s area * Cos (phy)

Where P =relative pressure
U =Velocity magnitude

Value of c/s area and (phy) is known to me and it is constant.

Can any one help me how can i do it in the FLUENT ?????

I have also attached pressure and velocity graph for more clarification.

Similarly, I want the power distribution.

Please, it is URGENT.

Thanking you,

I do not know how exactly you can do this but I think you've to write a journal and define a new parameter in it. So you can get a report by using this parameter.
Any one has any better idea?I'm eager to know the exact way!

I think you can use from fluent a custom field function (?)

Or you can write your own udf to export in a file your results..
