Class
    Foam::swirlInletVelocityFvPatchVectorField
 
Description
    Velocity inlet boundary condition creating axial, radial and tangential
    velocity fields specified by functions of time and radius or by a given
    angular speed.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        origin       | Origin of rotation      | no          | patch centre
        axis         | Axis of rotation        | no          | patch normal
        axialVelocity| Axial velocity [m/s]    | yes         |
        radialVelocity | Radial velocity [m/s] | yes         |
        omega        | Angular velocity of the frame | no |
        tangentialVelocity | Tangential velocity [m/s] | no  |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            swirlInletVelocity;
        origin          (0 0 0);
        axis            (0 0 1);
        axialVelocity   constant 30;
        radialVelocity  constant 10;
        tangentialVelocity  constant 100;
    }
    \endverbatim
 
    The \c axialVelocity, \c radialVelocity and \c tangentialVelocity
    entries are Function2 of time and radius, see see Foam::Function2s. The \c
    omega is a Function1 of time, see Foam::Function1s.
