Fully 3D ship hydroelasticity: Monolithic versus partitioned strategies for tight coupling

This paper analyzes the partitioned and monolithic strategies to simulate tightly coupled hidroelastic problems. The seakeeping hydrodynamics solver used is based on a first-order linear time-domain FEM model with forward speed double-body linearization. structural dynamics full 3D corotational shell elements accounting for geometric non-linearity. Both solvers are implemented under same programming framework, which allows implement strategy, minimize communication overheads of strategy. Two case studies test compare coupling: flexible catamaran in oblique waves, large floating reticulated structure made fiber reinforced plastic. In both cases, strategy between three four times faster than project has been developed H2020 FIBRESHIP aimed at developing technology design build large-length vessels polymers.
