What do you, that I some Howe should run the simulation all over again?

If you find out that you did not simulate what you needed to simulate, then yes, you need to do it again.
But the good news is that steady-state is much faster than transient. I don't know why you did transient in the first place...

Its no purpose to run a LES simulation with steady state, off course I am simulating transient. Thank you Pakk but that is not a solution to my problem, it is much easier with UDF if I can get the script right

If you think steady state LES has no purpose, then don't do it. You are free to spend a lot of computation time to get transient effects into your LES, and later on remove all those transient effects by making the time-average.

[edit: removed unnecessary details]
What I am going to say now might make you angry, but be aware that is not my goal. To write code, you need to be accurate and patient, and I don't think you are sufficiently developed in those competences yet.
This is all based on the little interaction I had with you in this thread, so I may be completely wrong, but otherwise I would advise you to avoid writing UDFs in the near future.

Yes you are right, No I really tried with the UDF manual, otherwise I could not have done this script even if it may be wrong. Its just that my simulations will take quite some time and I don't have the time to run those simulations again.
But I apologize if I was rude

No problem. I didn't feel you were rude, only inaccurate. Good luck!
