Class
    Foam::functionObjects::sixDoFRigidBodyControl
 
Description
    Convergence control based on the 6-DoF motion state.
 
    The body linear and angular velocities are averaged over a specified time
    window and compared to specified velocity convergence criteria and the run
    stopped after writing the current time results, if the criteria are met.
 
    Example of function object specification:
    \verbatim
    sixDoFRigidBodyControl
    {
        type           sixDoFRigidBodyControl;
        libs           ("libsixDoFRigidBodyState.so");
 
        angleUnits     degrees;
 
        window                      1;
        convergedVelocity           (1e-2 1e-2 1e-2);
        convergedAngularVelocity    (5 5 5);
    }
    \endverbatim
 
    Note the units of the \c convergedAngularVelocity are specified by the \c
    angleUnits entry.
 
Usage
