Description
    This boundary condition provides a log-law type ground-normal inlet
    boundary condition for the turbulent kinetic energy (i.e. \c k)
    for homogeneous, two-dimensional, dry-air, equilibrium and neutral
    atmospheric boundary layer modelling.
 
    The ground-normal \c k profile expression:
 
        \f[
            k = \frac{(u^*)^2}{\sqrt{C_\mu}}
            \sqrt{C_1 \ln \left( \frac{z - d + z_0}{z_0} \right) + C_2}
        \f]
 
    where
    \vartable
      k        | Ground-normal turbulent kinetic energy profile [m^2/s^3]
      u^*      | Friction velocity                              [m/s]
      C_\mu    | Empirical model constant                       [-]
      C_1      | Curve-fitting coefficient for \c YGCJ profiles [-]
      C_2      | Curve-fitting coefficient for \c YGCJ profiles [-]
    \endvartable
 
    Required fields:
    \verbatim
        k    | Turbulent kinetic energy                         [m2/s2]
    \endverbatim
 
Usage
    Example of the boundary condition specification:
    \verbatim
    inlet
    {
        // Mandatory entries (unmodifiable)
        type            atmBoundaryLayerInletK;
 
        // Mandatory/Optional (inherited) entries (unmodifiable)
        ...
        flowDir         (1 0 0);    // not used
        zDir            (0 0 1);    // not used
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                         | Type | Reqd | Deflt
      type      | Type name: atmBoundaryLayerInletK   | word | yes  | -
    \endtable
