Abstract
This paper extends the QALE-FEM (quasi arbitrary Lagrangian–Eulerian finite element method) based on a fully nonlinear potential theory, which was recently developed by the authors [Q.W. Ma, S. Yan, Quasi ALE finite element method for nonlinear water waves, J. Comput. Phys, 212 (2006) 52–72; S. Yan, Q.W. Ma, Application of QALE-FEM to the interaction between nonlinear water waves and periodic bars on the bottom, in: 20th International Workshop on Water Waves and Floating Bodies, Norway, 2005], to deal with the fully nonlinear interaction between steep waves and 2D floating bodies. In the QALE-FEM method, complex unstructured mesh is generated only once at the be...
