MIKE 21, developed by (Danish Hydraulic Institute), is a market-leading professional software suite for two-dimensional (2D) free-surface flow modeling. It is widely used by engineers and researchers to simulate hydrodynamics
The MIKE 21 system operates on the numerical solution of 2D Reynolds-averaged Navier-Stokes equations
DHI MIKE 21 is far more than just a software package; it is a comprehensive, industry-proven ecosystem for water modeling. Its capability to simulate a vast range of interconnected physical, chemical, and biological processes, from coastal currents to urban floods and ecosystem health, makes it an indispensable strategic asset for any professional facing modern water challenges. dhi mike 21
Because of its versatility, MIKE 21 is applied across multiple engineering and environmental sectors:
At its core, MIKE 21 is a 2D modelling engine solving the incompressible Reynolds Averaged Navier-Stokes equations (RANS) using the depth-integrated approach (shallow water equations). It assumes that horizontal length scales are significantly larger than vertical scales, making it ideal for most coastal and fluvial environments.

MIKE 21 is a professional engineering software package developed by DHI used to simulate in a wide range of water bodies, including rivers, lakes, estuaries, bays, coastal areas, and oceans. While DHI offers other specialized modeling systems like MIKE 11 for 1D river flows and MIKE SHE for fully integrated surface and groundwater hydrology, MIKE 21 fills the crucial role of 2D and quasi-3D simulations , providing a detailed, spatially-distributed understanding of water processes. Because of its versatility, MIKE 21 is applied
The Classic engine utilizes a Cartesian grid where the study area is divided into uniform square cells. This grid setup is highly efficient for localized, structured environments like small harbors, simple channels, or straightforward laboratory flumes. While computationally fast, it can struggle to smoothly map highly irregular or curved coastlines without using very small, resource-intensive cell sizes. 2. MIKE 21 FM (Flexible Mesh)
