MIKE 21 and MIKE 3
Supercharge your marine water modelling projects
MIKE 21 and MIKE 3 are advanced software suites for simulating and analysing water flow, currents, wave conditions, and processes in marine and coastal environments. With robust visualisation tools and data management capabilities, these software solutions empower users to effectively interpret simulation results. Widely embraced by engineers, scientists, and environmental professionals, they find application in coastal engineering, water resource management, environmental impact assessment, and climate change adaptation planning.
MIKE 21 specialises in two-dimensional (2D) modelling, offering precise simulations of water flow and movement in coastal areas, estuaries, and rivers. It enables accurate predictions of water levels, currents, temperature variations, and flood occurrences, excelling in managing intricate bathymetry and external forces like wind effects.
Conversely, MIKE 3 extends hydrodynamic modelling capabilities into three dimensions (3D), providing an exhaustive understanding of water flow dynamics. It addresses phenomena such as wave-induced currents, storm surges, and weather-related influences, proving indispensable for detailed environmental evaluations, particularly in complex marine settings.

Why choose MIKE 21 or MIKE 3?
Choose the modules that best suit your needs
Pick and choose from a selection of modules that target specific concerns. Alternatively, pre-bundled software subscriptions provide great value.
Marine PP, Hydrodynamics, and Transport
Marine Pre & Post-Processing
Start your data visualisation journey with Marine Pre & Post-Processing (PP), an integrated environment within MIKE Zero for easy data input, analysis, and result presentation.
- Generate boundary conditions quickly and easily
- Create and edit 2D/3D grids and detailed computational meshes
- Animate results in Google Earth and create amazing 3D video presentations
- Speed up model creation with access to digital bathymetric data
- Enhance productivity with sensitivity analysis and auto-calibration features
- Access data in MATLAB, Python, QGIS and other programming languages
See the MIKE Zero Pre & Post-Processing User Guide for full details.
Hydrodynamics
The Hydrodynamic (HD) module solves the equations for the conservation of mass and momentum as well as for salinity and temperature in response to a variety of forcing functions.
- Specify a variety of hydrographic boundary conditions, initial conditions, bed resistance and wind forcing
- Include different types of sources and sinks as well as different structures
- Treat density variations in different manners
- Include radiation stresses from wave simulations
- Choose from rectangular grid, nested grids or flexible meshes
- Seamlessly integrates with other modules for coupled modelling
See the MIKE 21 HD User Guide and MIKE 3 HD User Guide for full details.
Transport
Rely on the Transport (AD) module to quickly assess your water quality concerns by simulating the spreading and fate of tracers, dissolved, or suspended matter.
- Describe the temperature, salinity, and density of substances subject to linear decay and heat dissipation
- Analyse complex discharges via connected source-sink dynamics to understand re-circulation or variations in habitat quality
- Identify zones of accumulation and poor flushing using multiple tracers to support water quality screening
- Integrate with MIKE ECO Lab for modelling eutrophication, coliform bacteria fate, and heavy metal compounds
