Description
    This boundary condition provides a log-law type ground-normal inlet
    boundary condition for the turbulent kinetic energy dissipation rate
    (i.e. \c epsilon) for homogeneous, two-dimensional, dry-air, equilibrium
    and neutral atmospheric boundary layer modelling.
 
    The ground-normal \c epsilon profile expression:
 
        \f[
            \epsilon = \frac{(u^*)^3}{\kappa (z - d + z_0)}
            \sqrt{C_1 \ln \left( \frac{z - d + z_0}{z_0} \right) + C_2}
        \f]
 
    where
    \vartable
      \epsilon | Ground-normal TKE dissipation rate profile     [m^2/s^3]
      u^*      | Friction velocity                              [m/s]
      \kappa   | von Kármán constant                            [-]
      z        | Ground-normal coordinate component             [m]
      z_0      | Aerodynamic roughness length                   [m]
      d        | Ground-normal displacement height              [m]
      C_1      | Curve-fitting coefficient for \c YGCJ profiles [-]
      C_2      | Curve-fitting coefficient for \c YGCJ profiles [-]
    \endvartable
 
    Required fields:
    \verbatim
        epsilon   | Turbulent kinetic energy dissipation rate   [m2/s3]
    \endverbatim
 
Usage
    Example of the boundary condition specification:
    \verbatim
    inlet
    {
        // Mandatory entries (unmodifiable)
        type            atmBoundaryLayerInletEpsilon;
 
        // Mandatory/Optional (inherited) entries (unmodifiable)
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property  | Description                             | Type | Reqd | Deflt
      type      | Type name: atmBoundaryLayerInletEpsilon | word | yes  | -
    \endtable
 
    The inherited entries are elaborated in:

     - \link inletOutletFvPatchField.H \endlink
