I am having a case setup where I hvae the following boundary conditions:

Inlet - totalPressure, totalTemperature, pressureDirectedInletVelocity
Outlet - staticPressure ( fixedValue)

I want to do LES simulation of the case.


How can I generate fluctuations in the inlet velocity if I have given pressureDirectedInletVelocity boundary condition at inlet ? Is it possible to do so in OpenFoam.
