Application of a two-way partitioned method for predicting the wave-induced loads of a flexible containership
Application of a two-way partitioned method for predicting the wave-induced loads of a flexible containership
The symmetric motions and wave-induced loads of a flexible S-175 containership are investigated using a two-way implicit coupling between RANS/CFD and Finite Element Method, STARCCM+ and Abaqus, respectively. The meshing strategy adopted for the two-way coupling (co-simulation) is presented and discussed. The numerical predictions of symmetric motions and acceleration and vertical bending moment RAOs are compared against experimental measurements and other available numerical predictions. The nonlinearities in the wave-induced bending moments, expressed as higher order harmonics of the wave encounter frequency, 2-node contribution and asymmetry in hogging and sagging loads are predicted with good overall accuracy. The influence of structural damping on the nonlinear resonant vibration is also demonstrated.

Abstract
The symmetric motions and wave-induced loads of a flexible S-175 containership are investigated using a two-way implicit coupling between RANS/CFD and Finite Element Method, STARCCM+ and Abaqus, respectively. The meshing strategy adopted for the two-way coupling (co-simulation) is presented and discussed. The numerical predictions of symmetric motions and acceleration and vertical bending moment RAOs are compared against experimental measurements and other available numerical predictions. The nonlinearities in the wave-induced bending moments, expressed as higher order harmonics of the wave encounter frequency, 2-node contribution and asymmetry in hogging and sagging loads are predicted with good overall accuracy. The influence of structural damping on the nonlinear resonant vibration is also demonstrated.
