In this 1-day in-person course (conducted twice), we will explore how Delft3D FM supports detailed hydrodynamic modelling of rivers, coasts, or urban cities utilizing a flexible mesh concept. Through a combination of lectures and hands-on exercises, the course introduces grid generation for flexible grids, unique bathymetry interpolation methods, quickly setting up and running two-dimensional (2D) coastal – estuarine D-Flow FM models and analyzing results using the Delft3D FM build-in and/or third-party post-processing tools.
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, flooding, 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 grids in 1D-2D-3D. D-Flow FM is the successor of Delft3D-FLOW and soon of SOBEK-1DFLOW.
Similar to Delft3D-FLOW, D-Flow FM is capable of handling curvilinear grids that provide very good performance in terms of computational speed and accuracy. Furthermore, 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, modifying existing ones, or locally increasing resolution when/where needed that help significantly save computation time. Both Cartesian and spherical coordinate systems are supported. The grid generation tool RGFGRID includes new grid generation and orthogonalization algorithms for the construction of unstructured grids.
