| Abstract |
Fluid-flexible floating structure interaction studies in Computational Fluid Dynamics (CFD) remain predominantly two dimensionals, limiting the exploration of three dimensional effects crucial for the design of Very Flexible Floating Structures (VFFSs). To address this gap, this work extends a previously developed Applied Element Method (AEM) beam formulation into a plate formulation within the coupling of the weakly compressible Smoothed Particle Hydrodynamics (SPH) solver of DualSPHysics and the Multibody Dynamics (MBD) module of Project Chrono. The new structural scheme demonstrates comparable accuracy to established non-linear shell formulations in problems dominated by large displacements. Incorporated into an SPH variable resolution scheme for the fluid phase, the proposed formulation is validated experimentally for flexible floating plates, confirming both the accuracy of the three dimensional AEM framework in fluids and the robustness of the coupling under variable resolution conditions. Thus, the developed fluid-flexible structure interaction model establishes a foundation for advancing the design analysis of VFFSs, including future applications with complex mooring line configurations or large-scale interconnected modular arrays. |
