Very recently, researchers carried out the numerical simulation cases including seakeeping tests and reported the results on the Gothenburg 2010 CFD Workshop.
It can be seen from Fig.2 that the simulation results are well agree with the target results, and the NWT can offer high precision wave environment for the seakeeping simulation.
The transfer functions obtained by CFD are evident fine than that calculated by strip theory method.
The strip theory method has difficult to treat the nonlinear motion; by contrast, the CFD method has the advantage to cope with the nonlinear motion.
