Class
    Foam::waveAlphaFvPatchScalarField
 
Description
    This boundary condition provides a waveAlpha condition. This sets the phase
    fraction to that specified by a superposition of wave models. All the
    wave modelling parameters are obtained from a centrally registered
    waveSuperposition class.
 
Usage
    \table
        Property  | Description                            | Req'd? | Default
        phi       | Name of the flux field                 | no     | phi
        liquid    | Is the alpha field that of the liquid? | no     | true
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type        waveAlpha;
        libs        ("libwaves.so");
        liquid      true;
    }
    \endverbatim
