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.

There is no one size fits allMany information started afloat after many organizations announced WFH. Too many people have written information on do this, do that, don't do that and so on. Everyone writes from what they know and what has worked for them. It's okay to look up the information from them, but it isn't necessary to follow them as long as it works for you. What worked for them might not work for you. Try once to see if it works for you, if not learn from it. Find out what works for you and continue.I have seen in multiple blogs that people are saying that dress like you want to dress for work. Take a bath first, eat breakfast, do not wear pajama, do not work from the bedroom or on the bed, etc. I have seen and worked with people who feel very comfortable working on wearing comfortable wear and from the bed. They have produced better results too. So, take advice only as a piece of advice from those posts. Coaching agile transitions
