CFD Online Discussion Forums - turbulentDFSEMInlet for LES imulation for naca0012 aerofoil

I am trying to use turbulentDFSEMInlet at the inlet for simulation flow over aerofoil (The domain is attached below
domain size ( 5c upstream, 10 c downstream and spanwise 0.1 c ) c is the chord length (c=0.3048 m)

inlet condition

Code:

    inlet

    {

        type            turbulentDFSEMInlet;

        delta           2;

        nCellPerEddy    3;

        mapMethod       nearestCell;

        R               uniform (0.5 0 0 0.5 0 0.5);

        U               uniform (71.3 0 0);

        L               uniform 0.17;

        value           uniform (0 0 0);

    }

After running the simulation for the first time step, the only 5 eddy is generated at the inlet

Does anyone have used this boundary condition for external flow case ?
