Dear Jonkman,
Thank you for your quickly response.
According to your expression of kinematic equation (v_Total = v_Trans + omega x position), the term of “position” depend on center gravity location of full floating offshore wind turbine system. That’s what I would like to ask you in second question. This location (CG) may be significant effect to additional velocity on any point rotor blade.
Other question I am little bit confuse is to involve to second-order hydrodynamic of FAST program. According to your discussion (Questions about the HydroDyn Module), if pre-processing program (WAMIT, SWIM, AQWA, etc) can prepare second order hydrodynamic (second-order exciting force,…), is it directly use by FAST code? As I understand the following paper, WAMIT was used to create second-order hydrodynamic data for FAST code.

I am looking forward your help.
