Class
    Foam::waveVelocityFvPatchVectorField

Description
    This boundary condition provides a waveVelocity condition. This sets the
    velocity 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
    \endtable

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