Class
    Foam::solidBodyMotionFunctions::tabulated6DoFMotion
 
Description
    Tabulated 6DoF motion function.
 
    Obtained by interpolating tabulated data for surge (x-translation),
    sway (y-translation), heave (z-translation), roll (rotation about x),
    pitch (rotation about y) and yaw (rotation about z).
