Abstract

It is of high importance to study the wave interaction with cylinder structures because they are the common types of installations in coastal and offshore engineering. In this paper, a 3-D hybrid model based on the smoothed particle hydrodynamics (SPH) and the Quasi Arbitrary Langangian-Eulerian Finite Element Method (QALE-FEM) is used to study the interaction of focused waves with fixed cylinder. The hybrid model has advantages in simulating the focused waves and cylinder interactions in terms of accuracy and efficiency by making use of respective advantage of the above-mentioned two methods. In this hybrid model, the SPH method is used in the near-field interaction between the focused waves and cylinder and the QALE-FEM method is adopted for the wave generation at the SPH boundaries.
