Class
    Foam::coneVelocityLagrangianVectorFieldSource
 
Description
    This source condition provides a conical velocity profile, characterised by
    a mean velocity and inner and outer cone angles. The mean velocity is a
    Function1 and can vary with time. This is likely to be used in conjunction
    with a point injection model.
 
Usage
    \table
        Property      | Description                       | Required? | Default
        Umean         | The velocity along the centreline | yes       |
        thetaInner    | The inner cone angle              | yes       |
        thetaOuter    | The outer cone angle              | yes       |
    \endtable
 
    Example specification:
    \verbatim
    <LagrangianModelName>
    {
        type            coneVelocity;
        Umean
        {
            type            table;
            values
            (
                (0 (0.1 0 0))
                (0.5 (0.5 0 0))
            );
        }
        thetaInner      15 [deg];
        thetaOuter      22.5 [deg];
    }
    \endverbatim
