I use a software package called OrcaFlex to model the behavior of a buoy in ocean waves. I would like to share OrcaFlex questions in this forum - hope some users are out there! Here is a starter question: For a 6D buoy, I extracted the 'Dry Length' after the simulation completed. The value of the Dry Length sometimes slightly exceeds the actual height of the buoy, even though this would not seem to be possible given the formula from the manual, Dry Length = (cylinder length) × (cylinder volume above surface) / (cylinder total volume). Any insights?
