Q: Is the added mass coefficient reported by MOSES the total added mass? In other words, will the total added mass be the displacement x the added mass coefficient reported or displacement x (1 + added mass coefficient reported).
REV 7.01

A: This is a normal confusion. what we report is the added mass. What many others report is the hydrodynamic mass. The differ by 1; i.e. the hydrodynamic mass is the basic mass plus the added mass.
