Description
    This boundary condition provides a log-law type ground-normal inlet
    boundary condition for the streamwise component of wind velocity
    (i.e. \c u) for homogeneous, two-dimensional, dry-air, equilibrium
    and neutral atmospheric boundary layer modelling.
 
    The ground-normal streamwise flow speed profile expression:
 
        \f[
            u = \frac{u^*}{\kappa} \ln \left( \frac{z - d + z_0}{z_0} \right)
        \f]
 
        \f[
            v = w = 0
        \f]
 
    where
    \vartable
      u        | Ground-normal streamwise flow speed profile    [m/s]
      v        | Spanwise flow speed                            [m/s]
      w        | Ground-normal flow speed                       [m/s]
      u^*      | Friction velocity                              [m/s]
      \kappa   | von Kármán constant                            [-]
      z        | Ground-normal coordinate component             [m]
      d        | Ground-normal displacement height              [m]
      z_0      | Aerodynamic roughness length                   [m]
    \endvartable
 
    Required fields:
    \verbatim
        U   | Velocity                                          [m/s]
    \endverbatim
 
Usage
    Example of the boundary condition specification:
    \verbatim
    inlet
    {
        // Mandatory entries (unmodifiable)
        type            atmBoundaryLayerInletVelocity;
 
        // Mandatory/Optional (inherited) entries (unmodifiable)
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                              | Type | Reqd | Deflt
      type      | Type name: atmBoundaryLayerInletVelocity | word | yes  | -
    \endtable
