intro story D-Flow FM


D-Flow Flexible Mesh

D-Flow Flexible Mesh (D-Flow FM) is the new software engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. Together with the familiar curvilinear meshes from Delft3D 4, the unstructured grid can consist of triangles, pentagons (etc.) and 1D channel networks, all in one single mesh. It combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration, resulting in:

  • Easier 1D-2D-3D model coupling, intuitive setup of boundary conditions and meteorological forcings (amongst others).
  • More flexible 2D gridding in delta regions, river junctions, harbours, intertidal flats and more.
  • High performance by smart use of multicore architectures, and grid computing clusters.
An overview of the current developments can be found here.
The D-Flow FM - team would be delighted if you would participate in discussions on the generation of meshes, the specification of boundary conditions, the running of computations, and all kinds of other relevant topics. Feel free to share your smart questions and/or brilliant solutions! 


We have launched a new website (still under construction so expect continuous improvements) and a new forum dedicated to Delft3D Flexible Mesh.

Please follow this link to the new forum: 

Post your questions, issues, suggestions, difficulties related to our Delft3D Flexible Mesh Suite on the new forum.

The Framework  idea is to build complex productsTake the example of constructing a house. Consider, an under-construction house is handed over to you with the foundation and pillar set. You can start building it further with the groundwork laid, but you cannot begin living in the house.You will need walls, rooms, interiors, and furniture to live in. You will be provided with the guidelines to construct the rooms, windows, etc. The choice of building it as per your choice in making it a better place to live in lies with you.You have the groundwork, guidelines, and choice. How it turns out to be lies in the hands of you. That's called a framework.Scrum is a framework, which can be used by product development teams to self-organize to solve complex and adaptive problems. The idea is to build complex products. ICP-CAT certification
