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?
if you are looking to spatial gradients you go in the console and type solve then set then expert then start answering the questions till you get
answer it with yes. To accept default answers just hit enter. Run for more iteration and you can access the gradients as post-processing.
with respect to what?
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.
Thanks a lot.
