Procedure to plot Swirl Number in Fluent

Few days back I posted a thread on how to calculate swirl number in Fluent.
I contacted Ansys support and here is the way. I hope it will help others:
The swirl number is defined as the radius-weighted ratio of axial flux of angular momentum to the axial flux of axial momentum.
SWIRL_NUMBER = FLOWRATE(radius*tangential-velocity) / FLOWRATE(radius*axial-velocity)
You can use custom field functions to obtain radius*tangential-velocity and radius*axial-velocity.
Some users use a reference radius in the denominator such that:
Denominator = radius_ref*FLOWRATE(axial-velocity)

thanks a lot for the definition.
i am modelling a cyclone separator unit and is interested in obtaining the swirl number decay downstream.
I am however having a difficulty in obtaining the radius weighted and flow rate in custom field function.
Thanx a bunch
