MIKE 21 Boussinesq Waves

Analyse wave disturbances in ports, harbours and coastal areas

Analyse short and long period wave conditions to support planning and design with this go-to software designed to reproduce the combined effects of all important wave phenomena.

Why MIKE 21 Boussinesq Waves?

Assess wave dynamics inside harbour basins by reproducing the combined effects of all important wave phenomena

Understanding wave disturbance inside harbour basins is one of the most important factors when selecting a construction site or determining optimum harbour layout in relation to acceptable wave disturbance, ship movements, mooring arrangements and handling downtime. Rely on MIKE 21 Boussinesq Waves (BW) for the most comprehensive wave studies. Reproduce the combined effects of all important wave phenomena including shoaling, refraction, diffraction, wave breaking, bottom friction, moving shoreline, partial reflection and transmission, non-linear wave-wave interaction, frequency spreading and directional spreading.

Investigate the potential for seiching/resonance for comparisons with alternative layouts

Phenomena, such as wave grouping, surf beats, generation of bound subharmonics and super-harmonics and near-resonant triad interactions, can also be modelled using MIKE 21 Boussinesq Waves. Assess low-frequency motions in existing as well as new harbours through a combination of simulations with natural wave spectra. Investigate the potential for seiching/resonance and identify the natural frequencies, particularly useful for comparisons with alternative layouts.

Featured software subscription package

Ports and Maritime

This affordable subscription package includes MIKE 21 Boussinesq Waves, MIKE 21 Mooring Analysis, MIKE 3 Wave FM and MIKE 21 Spectral Waves plus additional modelling tools for port and maritime applications.

Additional capabilities & unique features

Regardless of how well you undertake your modelling work, clear communication of results is crucial to its value and recognition. Present time series plots (1D, 2D and 3D), data checking by graphical and tabular view, statistics, 2D/3D animations and time series analysis (using WSWAT) analysis with specialised tools. Create plots and instantaneous 2D animations of wave disturbance coefficient and simulated surface elevations with the Plot Composer Tool. Create realistic 3D scenes, including buildings, ships or other solids, visualise waves in 3D, produce professional fly-through animations and more with MIKE Animator Plus. Bonus: MIKE Animator Plus is included in all software subscription packages.

Using the Generate Sponge and Porosity Layer Map Tool, you can easily create sponge (or absorbing) layers along model boundaries to provide radiation boundary conditions, which absorb wave energy propagating out of the model area. These sponge layers may also be used along shorelines. Simulate partial wave reflection and/or wave transmission through various types of structures by creating a porosity layer map using this same tool.

MIKE 21 Boussinesq Waves also allows you to predict and analyse the impact of ship-generated waves (wake wash) in ports, harbours and coastal areas. Essential boundary conditions (at internal or open boundaries) for the models can be obtained from 3D computational fluid dynamics (CFD) models, experimental data, full-scale data and/or empirical relationships.

To support the preparation of wave boundary conditions, MIKE 21 Boussinesq Waves includes multiple options for internal wave generation depending on the type of waves; regular, irregular or directional. Generate regular wave data with the Regular Wave Generation Tool and irregular and directional waves with theRandom Wave Generation Tool. These tools support the most widely used type of frequency spectra as well as user-defined spectra and directional distributions.

Providing MIKE21 Boussinesq Waves with a suitable bathymetry is essential for obtaining reliable results from the model. The Bathymetry Editor provides an efficient environment for creating, editing and presenting detailed digital bathymetries.

The deterministic output dialogue of MIKE 21 Boussinesq Waves allows the user to save time series of surface elevations in points, along transects or in domain areas for subsequent analysis and visualisation.

The computational engine of MIKE 21 Boussineq Waves has been parallelised using shared memory architecture. This provides faster simulations on systems with many cores.

Additional analysis (of both dfs0 and dfs2 data) including spectral, directional, filtering or crossing analysis of the model output can be made using the WS Wave Analysis Tool.

The phase-averaged output dialogue of MIKE 21 Boussinesq Waves allow users to save a large number of commonly used derived variables. Select between two types of phase-averaged wave statistics, cumulative and subseries. With Cumulative Statistics, the output items are updated regularly corresponding to a specific update interval. In the case of Subseries Statistics, the output items are set to zero at the update interval.
