Mike 21 — Dhi

Unlike older rigid grids, MIKE 21’s flexible mesh allows you to increase resolution only where it’s needed—like around a bridge pier or a narrow channel—without slowing down the entire simulation.

A powerful ecological modelling framework. Users can build custom water quality models (or choose from templates) to simulate:

The strength of MIKE 21 lies in its ability to integrate multiple physical processes. Its modular structure allows you to build a model as simple or as complex as your project requires.

The following overview explores the capabilities and applications of , a premier 2D numerical modeling system developed by DHI for simulating hydrodynamics, waves, and sediment transport in marine and coastal environments. Core Modeling Principles

The system requirements for DHI Mike 21 include: Unlike older rigid grids, MIKE 21’s flexible mesh

The classic Cartesian grid divides the modeling domain into equal square cells. It is highly efficient for simple geometries, open ocean modeling, or large-scale simulations where high resolution along complex shorelines is not critical. Flexible Mesh (FM)

Maintaining deep navigation channels is a multi-million-dollar challenge for global ports. MIKE 21 helps quantify sedimentation rates within channels, allowing port authorities to optimize capital and maintenance dredging schedules.
