DualSPHysics simulations of various wave-structure interactions

Abstract

With rapid advancement in ocean engineering, the accurate simulation of interactions between the waves and the structure becomes crucial for optimizing the design process and enhancing the safety and performance of such structures. The present study carries out a series of numerical simulations on wave-structure interactions under three different scenarios using the mesh-free Smoothed Particle Hydrodynamics (SPH) approach, including a fixed, freely floating and moored structure. An open-source code, based on the Dual Smoothed Particle Hydrodynamics Physics (DualSPHysics), is used as the implementation tool. To evaluate the performance of SPH together with the coupled mooring line model, the study compares the computed wave force, free surface elevation, float motion, and mooring forces with the documented data. For the mooring structure case, the RMSE error in computed wave surface elevation is 0.0056 m, 0.001 m in float motion and 0.72° in pitch angle, and 3.1 N in mooring force. The linear correlation coefficients were found to be around 1.0 while the amplitude errors of most physical quantities were in the range of 0.9 - 1.0. Besides, a comprehensive evaluation of key parameters in the model has been carried out to complement the limitations of previous model studies.
