reddy_reddy is on a distinguished road
Hi all,

I have mean wind velocity profile from the wind tunnel experiment. This experiment is for pressure measurement on tall buildings. The flow is turbulent flow. I would like to numerical simulation (LES) using FLUENT. I think for LES, we need to give fluctuating wind velocity profile as inflow boundary condition.
Please help me how to generate the fluctuating wind velocity profile from mean wind velocity profile for inflow boundary conditions.
Is there any option in FLUENT which automatically generates the fluctuating wind velocity profile from mean wind velocity profile?

Thank you in advance for all.

Raja.
