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:

Compiling Delft3D Version 2514

Compiling Delft3D Version 2514


I am trying to compile version 2514, downloaded from
DELWAQ Version
Delft3D-FLOW Version
Delft3D-WAVE Version

The when I compile the code I get:
========== Build: 64 succeeded, 8 failed, 8 up-to-date, 0 skipped ==========

Any ideas why I might have 8 failed?

Thanks in advance for any help.

Hi Jennifer,

- start with an empty directory
- download the source code (again)
- open VisualStudio with the proper solution
- build everything
- copy/paste the full contents of the output window into a text file
- post that text file here on the forum

Hi Adri,

Thanks for responding. After realising I have intel 2013, I used d_hydro_open_source_vs2010_intel13.sln and everything worked perfectly!

Kind regards,
