The HAWASSI is a software for simulating water wave.The acronym HAWASSI© stands for Hamiltonian Wave-Ship-Structure Interaction.

The Hamiltonian formulation calculates phase resolved waves in a dimension-reduced way (Boussinesq with exact or optimized dispersion); the interior fluid motion can be recovered in a post-processing step. The explicit time evolution with automatic time step conserves the approximate energy exactly and avoids instabilities and unwanted dissipation. Wave-Ship-Structure Interaction refers to waves affected by bathymetry, harbour walls, breakwaters, etc.

The software has been developed over the past years in collaboration with the University of Twente, Netherlands, with additional financial support of Netherlands Technology Foundation STW and Royal Netherlands Academy of Arts and Sciences KNAW.
