In the present paper, the recent developments to the Semi-Lagrangian-Splitting (SLS) solver introduced in [1] are discussed. The enhancements include the mesh reconstruction procedure and the use of a dual-mesh hybrid Finite Volume - Finite Element (FV-FE) technique that handles high mesh deformations efficiently and robustly. The numerical formulation is fully described and simulations are carried out to display the algorithm’s efficiency. More specifically, both classic oceanographic phenomena (internal waves) and the interaction between free-surface waves with an (emerging) breakwater are examined.

摘要

In the present paper, the recent developments to the Semi-Lagrangian-Splitting (SLS) solver introduced in [1] are discussed. The enhancements include the mesh reconstruction procedure and the use of a dual-mesh hybrid Finite Volume - Finite Element (FV-FE) technique that handles high mesh deformations efficiently and robustly. The numerical formulation is fully described and simulations are carried out to display the algorithm’s efficiency. More specifically, both classic oceanographic phenomena (internal waves) and the interaction between free-surface waves with an (emerging) breakwater are examined.
