The acronym HAWASSI stands for “Hamiltonian Wave-Ship-Structure Interaction”. The software is designed for all wave-related activities in coastal, ocean and marine engineering.

The first release in September 2015 provide tools that cover application areas such as

Pre-design of experiments in wave tanks to test ships
Optimal (re-) design of harbours, break waters, etc
Detection of coastal locations with minimal infragravity waves
Coastal effects of tsunamis
Extreme wave statistics
Multi-modal sea states with wind and swell waves

Future releases will include fully nonlinear coupling of waves and ship motions and data-assimilation methods.
