MIKE 21 Spectral Waves

Better predict the power of wind-waves

Calculate and analyse wave climates in offshore and coastal areas to accurately assess their impact on valuable assets using this proven spectral wind-wave model

Why MIKE 21 Spectral Waves?

Calculate wind-waves in all seas - easily and accurately

With MIKE 21 Spectral Waves (SW), you can precisely calculate the size of wind-generated waves and swell. Use this data as a solid and cost-effective foundation for a multitude of offshore or nearshore wave sensitive engineering activities. As your trusted workhorse, this advanced 3rd generation wind-wave modelling software offers a pioneering flexible mesh approach and highly efficient engine parallelisation.

Perform swift calculations of coastal wave climates by transforming offshore wave data using a truly spectral approach or by applying the rapid parameterised method

Efficiently transform offshore wave fields to coastal areas

MIKE 21 SW enables you to properly resolve the physical environment and governing wave processes by calculating wave climates at the regional and local scale when high spatial resolution is required. You can also down-scale or transform an offshore wave climate in truly dynamic spectral mode (2D wave spectrum calculated) or by using a fast parameterised mode (directional spectrum calculated), which is fit-for-purpose in many coastal applications.

Create reliable and fit-for-purpose wave data

Address wave problems where quantitative and detailed knowledge of wave conditions is important with this go-to physics-based modelling software. Feel confident you’ve accounted for all important physical phenomena controlling the growth, decay, propagation and transformation of wind-generated waves. Secure accurate and trustworthy wave simulation results.

Calculate wave-induced currents easily by coupling the wave model with MIKE 21/3 Hydrodynamics (HD). Add sediment transport and morphological models for subsequent assessment of erosion risks.

Seamlessly integrate MIKE 21 SW with other MIKE models

Perform dynamic coupled modelling including long term morphological simulations by seamlessly integrating MIKE 21 SW with other MIKE models. To drive the crucial wave-induced coastal currents responsible for sediment transport and hence morphological changes, calculated radiation stresses are used as input to MIKE 21/3 Hydrodynamic (HD) models. Boost your coupled modelling productivity with a user-friendly interface and wealth of built-in tools.

Perform quality work at rapid pace

It’s all about speed, accuracy and flexibility. Undertake multi-year wave hindcast studies faster than ever or deliver multiple ensembles in operational wave forecast systems with the software’s high-performance computing (HPC) capabilities. You can execute work in the Cloud and run MIKE 21 SW on both Windows and Linux operating systems. Furthermore, use your model output data directly in other MIKE applications such as MIKE 3 Wave FM, MIKE 21/3 Mud Transport (MT) and MIKE 21 Mooring Analysis (MA) for the most accurate and comprehensive studies.

Quickly set up spectral wind-wave models and execute multi-year wave simulations using HPC resources. Integrate with other models dynamically or as direct input data.

This affordable subscription package includes MIKE 21 Spectral Waves and MIKE 21/3 Hydrodynamics plus choose two extra modules from MIKE 21 or MIKE 3 – the most trusted tools in the market for ocean engineering.

Additional capabilities & unique features

This can be accomplished using either a constant threshold frequency or a dynamic threshold frequency with an upper frequency limit.

The software features an efficient MIKE Zero tool to support the generation and handling of unstructured meshes including the definition and editing of boundaries.

The Data Viewer is an efficient tool for the analysis and visualisation of unstructured data including processing of animations. A user can view meshes, spectra, bathymetries, results files of different format with graphical extraction of time series and line series from plan view and import of graphical overlays.

MIKE 21 SW provides an optimal degree of flexibility in describing bathymetry and ambient flow conditions through the use of both depth-adaptive and boundary-fitted unstructured mesh.

MIKE 21 SW includes an extensive range of model output parameters including wave, swell, air-sea interaction parameters, radiation stress tensor and spectra.

MIKE 21 SW is based on a flexible mesh, multiple core optimised run engine (Linux compilation also available).

The fully spectral formulation (FS) can be used in wave studies involving wave growth, decay and transformation of wind-generated waves and swell in offshore and coastal areas. The computationally less demanding directionally decoupled parametric formulation (DS) can be used for small scale wave transformation applications, those where fully developed seas are dominating.
