Class
    Foam::kLowReWallFunctionFvPatchScalarField

Description
    This boundary condition provides a turbulence kinetic energy wall function
    condition for low- and high-Reynolds number turbulent flow cases.

    The model operates in two modes, based on the computed laminar-to-turbulent
    switch-over y+ value derived from kappa and E specified in the corresponding
    nutWallFunction.

Usage
    \table
        Property     | Description             | Required    | Default value
        Ceps2        | model coefficient       | no          | 1.9
    \endtable

    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            kLowReWallFunction;
    }
    \endverbatim
