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.

stable code for GUI 4.04.00 and compiling tools

stable code for GUI 4.04.00 and compiling tools

I have GUI 4.04.00. But, FLOW version 6.03 only works in combination with GUI 4.04.00 (and higher), I see there have source code revision 62441, 7545 and 59659 that contain flow version 6.03. I am not so sure which one is the most stable source code?

After running python script of those source code, I saw some components under VC++ project (.vcxproj) and Intel Fortran project (.vfproj) were not recognized.

I have tried to compile those source codes with Visual Studio 2015 update 3 and Intel Parallel Studio XE 2016 update 4. But, I got the same problem during compiling code and build solution was always failed. I got comment:

Build started: Project: vs (tools_gpl\vs\vs), Configuration: Release x64 ------
  Could Not Find D:\delft3d62441\src\tools_gpl\vs\packages\vs\src\vs_l.c

VsHub.exe - Application Error

The application was unable to start correctly (0xc0000142). Click OK to close the program.

flex.exe - Application Error

The application was unable to start correctly (0xc0000142). Click OK to close the program.

Werfault.exe - Application Error

The application was unable to start correctly (0xc000012d). Click OK to close the application. 

I want to compile the code using visual studio community 2017 and Intel Parallel Studio XE 2018 update 3. But, I am not so sure how to check box of "Microsoft Foundation Classes for C++" and "Common Tools for Visual C++" in Visual studio community 2017 due to VS 2017 installation is much difference from VS 2015.

I have attached some captures about my problems.

I am really appreciate for your help.

Thank you

Note: I captured the picture after I installed VS 2015 and Intel Parallel Studio XE 2016. But,
