What formulation is used in the floatinginfo to compute the Rigid DOFs (Surge, Sway, Heave, Roll, Pitch, Yaw)?
For example, is the surge the x-motion of the center of mass or the mean of the x-motion of all floating particles?
center.x is the x-motion of the center of mass
surge is surge... so that only displacement from initial position in x-direction
Got it. How about the Pitch motion?
Thanks for quick response
Not sure if I understood the question.
Pitch is the angle along the y-axis
