... with the panel-free method in the frequency domain. In this paper, the effect of the m -terms and forward-speed/zero-speed Green functions (GFs) on the solutions are investigated using two Wigley hull ships. Computed motions, hydrodynamic coefficients, and added wave resistances were compared...

... domain is impractical owing to prohibitive computational costs, a highly efficient frequency domain approach was developed in a previous work, wherein the drag forces are linearized. The study showed that provided the geometric nonlinearity of the moorings/risers is insignificant, which often holds...

... ) are smaller than that of the first-order exciting force E r ( 1 ) ( t ) is implied, Eq. 1 can be solved in frequency domain. The solution of Eq. 1 can be expressed as 2 p s ( t ) = ∑ j = 1 N [ ζ j p s ( 1 ) ( ω j ) e i ( ω...
