2D and 3D hydrodynamic modelling using flexible mesh

This two-day, hands-on course will teach you the fundamentals of 2D & 3D hydrodynamic modelling (HD) and give you an introduction on how to set up a hydrodynamic model using MIKE 21/3 Flow Model HD FM models using flexible mesh bathymetry.

The hydrodynamic module of MIKE 21/3 Flow Models HD FM provides the basis for computations of processes performed in many other modules such as sediment and mud transport, transport of heat and suspended matter, oil spill, agent based modelling and ecology but can also be used as a stand-alone application. The module simulates unsteady flow taking into account density variations, bathymetry, sources and external forcing.

Typical application areas of MIKE 21/3 Flow Model HD FM include assessment of hydrographical conditions in stratified and nonstratified waters, coastal flooding and storm surge, oceanographic circulation studies and lake and reservoir hydrodynamics.


  • Selection of geographical coordinate system, bathymetry digitisation and vertical resolution (mesh)
  • Data organisation, import, editing and quality control
  • Fundamentals of 2D & 3D flow modelling
  • Setting up simple hydrodynamic models
  • Managing boundary conditions
  • Calibration and validation procedures
  • Using the utility software of MIKE 21/3 Flow Models
  • Analyses of model input and output
  • Interpretation of results and visualisation, including video animation
  • Hands-on exercises


Professionals in hydraulic engineering and management working with inland flooding, lakes, coastal areas or marine environment.

Experience with hydraulic modelling and the flexible mesh modelling complex is highly recommended either through experience or through following the course 'MIKE 21 Flow Model HD FM - 2D hydrodynamic modelling using flexible mesh' prior to the course.
