Timeaveraging of unsteady calculation
I want the timeaveraged values of the velocity derivatives and the turbulent kinetic energy in order to calculate the timeaveraged components of the turbulent Reynolds stress tensor. (I perform an URANS calculation) Do I have to programm it myself in an UDF, or are there other ways to obtain it?
Thanks

arent fluent RANS are time averaged Navier stokes equations
? i am confused 
Re: Timeaveraging of unsteady calculation
I am sure the values of a steady flow is timeaveraging by default. I am not sure whether the values of a unsteady flow is timeaveraging or not. If your case is a steady flow, you can acquire the velocity derivatives and turbulent kinetic energy directly from Fluent.
