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.

Compilation Using VS2010 and Intel Fortran XE 11

Hello Everybody,

I did compile Delft3D repositiories Tag version using VS 2010 and Intek Fortran 11 (update 12). I have attached my compilation result in this post. My compilation has got all executable created successfully. But I'm not sure of my examples are running without errors.
When run_flow2d3d batch file is executed under example_1 (standard) I get the below prompt :

Executing “ C:/Delft REPOSITORIES/bin/win32/flow2d3d/bin/d_hydro.exe TMP_config_flow2d3d_3144.xml”…
Couldn’t execute “C:\Delft”: no such file or directory while executing
“open $name “r””
<procedure “runcmd” line7>

“runcmd $command”

Press any key to continue . . .

Please help me solving this...

Hi Marshal,

Some scripts in the Delft3D code have problems with directory names containing spaces. Solving this is on our "To Do"-list.
Please use a directory name without white spaces.
