Dear Foamers,

I just started learning how to use openFoam and now I want to use the Atmospheric boundary layer profile as an inlet velocity along with the turbulent inlet.

inlet
{
type turbulentInlet;
referenceField nonuniform;
fluctuationScale (0.02 0.01 0.01);
}

inlet
{
type atmBoundaryLayerInletVelocity;
n (1 0 0);
z (0 0 1);
Uref 10.0;
Zref 20.0;
z0 uniform 0.1;
zGround uniform 0.0;
}

do you want to use both BC together?
it is impossible

you maybe want to change source code to consider turbulent flow along ABL condition

Hello Nima Samkhaniani,

I tried understanding the code but I wasn't able to figure out want exactly to change.So I came up with this solution
I performed two simulations.First with Atmospheric Boundary layer as the inlet for a few time steps.From the last time step, I got the non-uniform list of the inlet(which is the ABL).

In the second simulation, I used the Turbulent Inlet with nonuniform reference field and then copied the nonuniform list from the first simulation to the second simulation.It works fine .

boundaryField
{
inlet
{
type turbulentInlet;
fluctuationScale (0.20 0.20 0.20);
referenceField nonuniform List<vector>
10800
(
(3.45854 0 0)

)
;
}
