Through a combination of lectures and hands-on exercises, our Delft3D Flexible Mesh – Coastal Hydrodynamic Modelling course introduces grid generation for flexible grids, unique bathymetry interpolation methods, quickly setting up and running 2D coastal – estuarine models and analysing results using the Delft3D FM build-in post-processing tools, third-party tools and the upcoming 3D interactive modelling environment. Our course tutors and experts in the field of Integrated Coastal Zone Management (ICZM) and coastal engineering share their own case studies to share their experiences.
The Delft3D Flexible Mesh Suite (Delft3D FM) is the successor of the structured Delft3D 4 Suite. The Delft3D FM Suite can simulate storm surges, typhoons / hurricanes, tsunamis, detailed flows and water levels, waves, sediment transport and morphology, water quality and ecology and is capable of handling the interactions between these processes. 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.
