MIKE 21 Spectral Waves

Calculate wind-waves across all seas to aid marine infrastructure planning and design

MIKE 21 Spectral Waves (SW) is advanced software for simulating wave propagation and transformation. Tailored for environmental impact assessments and coastal infrastructure planning, it provides intricate simulations of wind-generated waves and swell, offering detailed forecasts of wave conditions in offshore and coastal areas.


Using spectral wave models, MIKE 21 SW accurately represents the energy distribution across different wave frequencies and directions, ensuring precise simulations of wave behaviour under various meteorological and oceanographic conditions. Equipped with features such as fluid mud dissipation and compatibility with high-performance computing, MIKE 21 SW offers comprehensive support for offshore energy, port design, and coastal resilience projects. Its user-friendly interface and powerful modelling capabilities empower engineers, researchers, and environmental consultants to analyse wave conditions, assess coastal risks, and design resilient coastal infrastructure with confidence.
