Delft3D Flexible Mesh: Coastal hydrodynamics
The key component of Delft3D FM is the D-Flow Flexible Mesh (D-Flow FM) engine for hydrodynamical simulations on unstructured and structured grids in 1D-2D-3D. D-Flow FM is the successor of Delft3D-FLOW and SOBEK-1DFLOW.
Like Delft3D-FLOW, D-Flow FM is capable of handling curvilinear grids, that provide very good performance in terms of computational speed and accuracy. Further to that, the grid may now also consist of triangles, quads, pentagons and hexagons. This provides optimal modelling flexibility and ease in setting up new model grids or modifying existing ones, or locally increasing resolution. 1D- and 2D grids can be combined, either connecting adjacent grids or a 1D grid overlying a 2D grid. Both Cartesian and spherical coordinate systems are supported. This facilitates tidal computations on the globe without imposing open boundary conditions. The grid generation tool RGFGRID includes new grid generation and orthogonalization algorithms for the construction of unstructured grids.
Some areas of applications
- Tide and wind-driven flow;
- Drying and flooding of inter-tidal flats;
- Density gradients due to a non-uniform temperature and salinity concentration distribution (density driven flows);
- Horizontal transport of matter on large and small scales;
- Hydrodynamic impact of engineering works such as land reclamation, breakwaters, dikes;
- Thermal recirculation of cooling water discharges from a power plant.
