Dhi Mike 21 |best| -

is a premier engineering software suite developed by (Danish Hydraulic Institute) for simulating 2D fluid dynamics and related processes in water bodies. As a industry-standard tool, it is used extensively by consultants, researchers, and government agencies to model environments ranging from small estuaries and rivers to expansive coastal and marine areas. Core Capabilities

DHI Mike 21 has a wide range of applications, including: dhi mike 21

Sand Transport (MIKE 21 ST): Used to calculate littoral drift and sediment transport, which is essential for studying beach erosion and harbor siltation. is a premier engineering software suite developed by

Overview of Mike 21

Typical workflows

  1. Gather bathymetry, topography, boundary conditions (tidal or riverine), meteorological forcing, and sediment/bed properties.
  2. Build 2D mesh or grid (structured or unstructured) matching geometry and resolution needs.
  3. Set physical processes to simulate (e.g., hydrodynamics + sediment transport + waves).
  4. Calibrate with measured water levels, flows, currents, and sediment data.
  5. Validate against independent observations.
  6. Run scenario simulations (e.g., storm surge, dredging, port layout, climate change).
  7. Analyze outputs: water level maps, velocity fields, sediment budgets, wave heights, morphological change.

Step 1: Pre-Processing (Mesh Generation)

Using the MIKE Zero Mesh Generator (or third-party tools like SMS), create a computational mesh. For structured grids, use the old MIKE 21 Grid Generator. For FM, ensure triangles have aspect ratios <10 and smooth transitions.

MIKE 21 is a premier engineering software suite developed by DHI (Danish Hydraulic Institute) for the two-dimensional (2D) modeling of water environments. It is the industry standard for simulating and analyzing hydrodynamics, waves, sediment transport, and water quality in coastal areas, estuaries, and rivers. Core Technology and Versions
