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.

Judgement of NYC

Judgement of NYCWe have been habituated from infancy to look at the world through the lens of Judgement to meet our needs. The Judgement come in all forms like
  • We do certain things that make us good
  • If we do certain things that make us evil.
  • If we do it this way it is right
  • If we do the other way it is wrong
  • We do things because we should
  • We should not do things this way since it’s not accepted etc..
These Perspectives that we carry on with us from our young age keeps us occluded from the new learnings, accept the emerging organizational behavior changes and stops us from collaboration.
What NVC teaches us is to translate our Judgement thoughts to our needs thoughts which is a solution-oriented communication. It encourages us to share the views openly and frankly and hear/understand others view clearly. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->Devops Online Training
