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.

Why do we need Scrum?
  • Scrum helps product teams maximize ROI for products in complex domains by reducing the Cost of Delay and Cost of Production through safe to fail experiments called Sprints.
  • Scrum makes clear the relative efficacy of your product management and work techniques so that you can continuously improve the product, the team, and the working environment.
Scrum is a framework, which can be useful in complex domains. Scrumis just enough to have some order in place and give you space to be creative in solving the problems. It advocates a time boxing approach called Sprints. Sprints are nothing but safe to fail experiments to uncover the problem to figure out the next steps.It's safe to fail because the amount money you would lose if the experiment fails is much lower compared to failing the whole product. It’s an experiment because there is always learning.Scrum encourages teams to review the system and improve it to increase the effectiveness of the team.Scrum enables product development teams to get frequent feedback from customers at the end of every Sprint. Devops Online Training
