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.

If you have to remove a Scrum event, what would that be?"One of the questions often asked in Scrum Master's interview is, "If you have to remove a Scrum event, what would that be?" As the team gets more self-organizing, the Sprint planning meeting at the start of the Sprint can be worked around through the Daily Stand-up. But the team needs to have reached that stage. However, grooming (backlog refinement) sessions would still continue since the dev team still needs to get the business and market perspective from PO.Every event of Scrum has been defined for a particular purpose. And none of it is negotiable or replaceable. In interview questions, it's fine to stick to one's ground. By replacing a scrum ceremony/event, you are actually telling the interviewer that you are willing to compromise on the ethos and objectives of Scrum. And you are quite flexible...and for you, Scrum doesn't mean anything.  ICP-CAT certification
