Detailed Description

User convenience class to handle the input of time-varying rotational speed in rad/s if omega is specified or rpm if rpm is specified.

Usage
For specifying the rotational speed in rpm of an MRF zone: 
    MRF
    {
        cellZone    rotor;

        origin     (0 0 0);
        axis       (0 0 1);

        rpm        60;
    }
or the equivalent specified in rad/s: 
    MRF
    {
        cellZone    rotor;

        origin     (0 0 0);
        axis       (0 0 1);

        omega      6.28319;
    }
or for a tabulated ramped rotational speed of a solid body: 
    mover
    {
        type            motionSolver;

        libs            ("libfvMeshMovers.so" "libfvMotionSolvers.so");

        motionSolver    solidBody;

        cellZone        innerCylinder;

        solidBodyMotionFunction  rotatingMotion;

        origin      (0 0 0);
        axis        (0 1 0);

        rpm         table
        (
            (0    0)
            (0.01  6000)
            (0.022  6000)
            (0.03  4000)
            (100   4000)
        );
    }
