Calculating RAOs in HAMS

Hi @YingyiLiu , as a continuation issue #26 , I see that when the RAOs are calculated for the 6DOF system using the added mass, radiation damping and excitation for in HAMS, they are quite different from WAMIT. I think this is because in the added mass and radiation damping as obtained from HAMS are the same as WAMIT (considering the dimensionalization of course), however for the excitation force, a+ib = -d-ic, where a+ib is the excitation for in WAMIT and c+id is the excitation force in HAMS. Would you know where this is coming from?
