How to calculate the derivative of k for turbulent flow in FLUENT?

Hi, I'm trying a case in Fluent and I need to calculate the value of the derivative of turbolent kinetic energy (I'm using k-w model for turbolence). Someone can help me?

    Sorry for the late. Yes, I'm looking to spatial gradients. Thanks a lot.

    So, if I don't want to run for more iteration after the calculation complete, I have to go in the console before run calculation?

    And another question: If I want the spatial derivative of a custom field fuction how should I do?

    For CFF that is not feasible: You will require to make it via UDF using the UDS way (store in UDS) then access its gradient (do not solve the UDS).

    For the first point better to have it from the beginning otherwise you might forget it.
