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.

Perspective is about an individual's ability

Perspective is about an individual's abilityA perspective is an attitude or an approach towards how one sees or thinks. It is also about an individual's ability to look at things which are also called a point of view. Naturally, when someone looks at something, they perceive it based on their experience, beliefs, morals, values, and so on. It is an interesting study to put something on the table and let people get a perspective out of it.There was an old chef. He made good tasty food. Everyone in the town loved the man’s food. He has 3 sons. All of them got their culinary skills from their father. Since it was a family run business whatever they cooked was that of their father’s recipe and taste. Everything was good as the town people liked their food so much.But the son’s did not know anything outside of the Oldman’s recipe. Just like any experienced businessman does, the Oldman decided to send his sons off to work outside the town and come back after 5 years. Five years were up and they all came back.Now when they wanted to cook their father’s basic recipe, they have three different ways of cooking them now. They didn’t know what the original recipe was. The Oldman asked them to cook the recipe in their own way and present it to him. They cooked and presented it to the old man. He tasted them all and they all tasted good but it wasn’t the original recipe at all. ICP-CAT certification
