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.

I want install Delft3D open-source about Fedora 20 , but i unknow as do its, i was reading in the URL and slide presentation in webinar "How to compile Delft3D on Linux" ( ).

For Ubuntu:
#Install subversion
sudo apt?get install subversion

For Fedora20:
it's code is replacet by
#Install subversion
yum install subversion

Help me please.

Hi Jhon,

Officially, Delft3D open source is only supported on RedHat/CentOS. For Ubuntu there are two very helpful files available in

Delft3D has been build successfully on Fedora a few years ago, but I'm not aware of recent trials. I'm pleased when you give it a try. Please keep us informed via this forum.
