Additional capabilities & unique features

• Single Grid, which is a classic rectilinear model that is easy to set up and with easy I/O exchange
• Multiple Grids, which is a dynamically nested rectilinear model with the ability to focus the grid resolution
• Flexible Mesh, which allows maximum flexibility for adapting grid resolution of the model domain

All Flexible Mesh and Single Grid engines support parallel processing. The Flexible Mesh (FM) engines show excellent performance when parallel processing is undertaken – also on a large number of computational cores. On multicore Windows computers, parallelisation is menu-driven and straightforward. The FM engines are also available for Linux, which gives the possibility to utilise High Performance Computing (HPC) systems. For the FM engines, the use of graphical processing units (GPU) is also supported and gives easy access to spectacular increases in simulation speed.

In addition to its variety of modules, MIKE 21/3 also includes a number of tools to optimise your work.
• Global tide data and tools for tidal analysis and prediction
• MIKE’s Climate Change Editor
• Cyclone wind generation and wind generation from pressure maps
• Advanced mesh and grid generators and editors
• Advanced tools for generation of graphical output
• An interface (API) for reading and modifying files in MIKE 21 or MIKE 3’s internal, binary format

MIKE C-Map offers model bathymetries generated fast and easy from an electronic chart database. MIKE ANIMATOR PLUS turns model results into amazing 3D video presentations.

MIKE 21 and 3 offer a choice of rectangular grid, nested grids or flexible meshes. This provides an optimal degree of flexibility in the representation of complex geometries and enables smooth representations of boundaries.

Well-functioning parallelisation techniques makes multicore execution efficient. Speed is further enhanced through the integrated use of GPU’s, engines that can execute under Linux and the possibility for execution under Microsoft Azure.

The FM series include a powerful, integrated system which, in a surprisingly easy manner, combines wave, flow and sediment transport models into a fully dynamic morphological model.

The MIKE3 flexible mesh hydrodynamics (HD) module includes both a non-hydrostatic (Navier Stokes equation) and hydrostatic (shallow water equation) solver. For modeling of internal wave generation due to density variation for example, the non-hydrostatic version is essential for capturing the correct behavior of the flow.

Model culverts, weirs and dikes to improve the accuracy and efficiency of morphodynamic simulations.

The simulation of outfall jets/plumes in a 3D environment is based on dynamic coupling of nearfield integrated jet solution and the farfield hydrodynamic flow model. This enables a user to accurately calculate the jet trajectory and rate of dilution in the nearfield region and incorporate the jet discharge into a Farfield flow model.

Both the full 3D Navier-Stokes equations (non-hydrostatic) and the 3D shallow water equations (hydrostatic) can be applied. Thus, the model consists of continuity, momentum, temperature, salinity and density equations and is closed by a turbulent closure scheme. The spatial discretisation of the governing equations is performed using a cell-centred finite volume method on triangular , quadrangular or mixed element domains, employing a shock-capturing Riemann solver to ensure robust and stable simulation of flows.

Accomplish this by making integrated near field-far field calculations with the Jet source.

Couple your coastal model with river channel and urban drainage networks to gain a more comprehensive understanding of the potential impact of coastal flooding on a community.

Integrated salinity and heat balance modules are included for coastal inundation simulations.

This capability makes MIKE 21 and 3 particularly applicable for global and regional sea scale applications.
