Hi All

I would like to perform a drift angle test to determine the various hydrodynamic coefficients on a shallow water vessel. The underwater clearance is just 0.6 m. I I have two queries
a) Since the vessel is inclined at an angle, is the force displayed in Report-->Force" measured with respect to the global axes or the vessel's local axes.
b) How to determine the acceleration coefficients from the simulation

thanks
