Class
    Foam::rotatingPressureInletOutletVelocityFvPatchVectorField
 
Group
    grpInletBoundaryConditions grpOutletBoundaryConditions
 
Description
    This velocity inlet/outlet boundary condition is applied to patches in a
    rotating frame where the pressure is specified.  A zero-gradient is applied
    for outflow (as defined by the flux); for inflow, the velocity is obtained
    from the flux with a direction normal to the patch faces.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | flux field name         | no          | phi
        tangentialVelocity | tangential velocity field | no  |
        omega        | angular velocity of the frame [rad/s] | yes    |
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            rotatingPressureInletOutletVelocity;
        phi             phi;
        tangentialVelocity uniform (0 0 0);
        omega           100;
    }
    \endverbatim
 
    The \c omega entry is a Function1 type, able to describe time varying
    functions.
 
Note
    Sign conventions:
    - positive flux (out of domain): apply zero-gradient condition
    - negative flux (into of domain): derive from the flux in the patch-normal
      direction
