Class
    Foam::waveAlphaFvPatchScalarField

Description

    Example of the boundary condition specification:
    \verbatim
    inlet
    {
        type            waveAlpha;
        value           uniform (0 0 0);
    }
    \endverbatim

Usage
    \table
        Property    | Description          | Required    | Default value
        type        | type: waveAlpha      | yes         |
        waveDict    | Dictionary specifying wave variables | no | waveProperties
    \endtable

Note
    - The value is positive inwards
    - May not work correctly for transonic inlets
    - Strange behaviour with potentialFoam since the U equation is not solved
