Dear support team,

I am running a LES simulation, I'm using the synthetic turbulence inlet using cs_uder_lew_inflow.f90.

I have a specific question about the example in the folder SRC/EXAMPLES.
In subroutine cs_user_les_inflow_advanced , Example 1:

utau = uref/20.d0

Is utau the friction velcoity, uref the bulk velocity which is specified as reference velocity?

Thanks,
Xiaoxue

Hello,

I am not completely sure for utau (but yes, I think it is the friction velocity), and in any case I confirm uref is the bulk velocity.

Best regards,

Yvan
