Dhi Mike: 21
The software features an intuitive Graphical User Interface (GUI) for mesh generation, boundary condition setup, and post-processing visualization.
It is a "one-stop-shop" for everything from coastal defense design (like seawalls) to analyzing the impact of marine sand mining or wave energy converters.
The defining feature of modern MIKE 21 is its . Older versions were purely structured. The FM allows:
: 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. dhi mike 21
to predict how water moves and interacts with its environment. By integrating continuity, momentum, and density equations, the model transforms static geographic data into a living, breathing digital twin of a water body. The Foundation: Bathymetry and Mesh Generation The journey of a "deep" simulation begins with bathymetry
Essential for coastal engineers, this module calculates non-cohesive sediment transport (sand, gravel). It predicts:

The Utility and Impact of DHI MIKE 21 in Hydrodynamic Modeling Introduction
provides a robust, scientifically proven platform for simulating free-surface flows and associated environmental processes in two dimensions. Its versatility—from flood hazard mapping to coastal zone management—makes it an essential tool for water engineers, environmental consultants, and researchers seeking defensible, high-resolution predictions of surface water dynamics.
Industrial projects near the coast—such as power plant cooling water intakes, desalination outfalls, and offshore wind farms—require strict environmental clearance. MIKE 21 simulates thermal plumes and brine dispersion to ensure compliance with mixing zone regulations. Advantages of Using MIKE 21 Older versions were purely structured
A powerful ecological modelling framework. Users can build custom water quality models (or choose from templates) to simulate:
The Flexible Mesh (FM) engine uses an unstructured grid made of triangles or quadrilaterals of varying sizes. This allows users to increase resolution in critical areas—like narrow channels or around port structures—while keeping a coarse resolution in the open sea. It optimizes computational efficiency while precisely mapping complex geometries. Key Modules of MIKE 21
