Dhi Mike 21 ((full))

Introduction

Key Physics: The engine simulates factors such as bottom shear stress, Coriolis force, momentum dispersion, and wind fields. MIKE 21-3 | Coast and Marine Water Modelling Software - DHI dhi mike 21

Key capabilities

• Hydrodynamics: Shallow-water and Navier–Stokes-based flow simulations for currents, water levels, and discharge.
• Waves: Spectral and phase-resolving wave models for wave propagation, transformation, and wave–current interaction.
• Sediment transport & morphology: Bed load and suspended load transport, erosion/deposition and morphological evolution.
• Water quality & ecology: Advection–diffusion transport, biochemical modules for nutrients, DO, algae/bloom modeling.
• Pollutant dispersion: Dye/fate modeling, tracer studies, and assessment of accidental releases.
• Structure interaction: Flow around piers, breakwaters, sea walls and intake/outlet structures.
• River & estuary applications: Tidal dynamics, salinity intrusion, stratification (coupled 3D options), floodplain inundation.
• Coupling & customization: Links to MIKE 3 (3D), MIKE HYDRO, MATLAB, and user-defined modules via APIs/scripting.

Integrated Ecosystem: It works seamlessly with other DHI tools. For example, you can couple MIKE 11 (1D) with MIKE 21 (2D) using MIKE FLOOD to model how a river interacts with an urban floodplain. Master 2D Modeling: Why DHI MIKE 21 is

Flexible Mesh (FM): Utilizes an unstructured mesh (typically triangles or quadrilaterals), allowing for higher resolution in critical areas like coastlines or around structures while maintaining coarser resolution in the deep ocean.
