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.

ScrumMaster as  a Facilitator:A facilitator is someone who helps a group of people improve their system by helping them identify the problems, solve the problems themselves and make their own decisions. Not by doing it for them; but by enabling them.  For example; Let’s say, in the middle of the sprint, the customer comes and changes the priority. PO can either accept the change or put it in the backlog.A ScrumMaster facilitates the decision making by creating the visibility of the impacts of accepting v/s not accepting the change in the current sprint, by showcasing short term and long term implication so that the PO can make a better decision.That’s facilitation in its simplest form. You are not doing the work for them, but you are enabling them to get their own work by helping them understand the purpose behind doing it, by creating the visibility of big picture, and the impacts of doing v/s not doing it.A ScrumMaster is that Facilitator who creates that visibility of the big picture so that the team is empowered to identify and solve problems and make well-informed decisions. Product Prototyping
