This utility initialises the U, k and epsilon fields (if available) to
the output of the atmBoundaryLayer model. This is the same model as used
in the atmBoundaryLayerInlet.* boundary conditions and in the
waveAtmBoundaryLayer wave model.
The settings for the initialisation are read from a
system/setAtmBoundaryLayerDict file and are identical to the settings
required by the other use cases. An example of the settings required
within a system/setAtmBoundaryLayerDict file is shown below:
zDir (0 0 1); // Vertical direction
flowDir (1 0 0); // Direction of far-field flow
Zref 20; // Reference height
Uref 10; // Speed at reference height
z0 uniform 0.1; // Roughness height
zGround uniform 0; // Ground height
