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.

Uncomplete compiling of the source code

Uncomplete compiling of the source code

Dear discussion members,

After finishing the compiling of the source code in Microsoft Visual Studio says that 7 errors occured.

When I go to the newly created binaries in my code in directory "bin\win32" there are several files missing, which are actually important. Those are:
...and a couple of other files, which seems less important.

When I want to execute "examples\01standard\run_flow2d3d.bat" the commander says: "Error: child killed: unknown signal". I think it has to do with the missing files named above. I know, that there is a comment about that Error message in the FAQ, which says that in this case ANOTHER dll is needed and can not be found. But this assumes that the file "flow2d3d.dll" exists, which is not the case here.
As the file "flow2d3d.dll" was not compiled correctly I can't run any of the examples (the "run" files in the example subdirectories standard, flow-wave, etc.).

There are other directories missing in the compiled code (in the created binaries), e.g. the "lib" directory in "bin\win32\flow2d3d". In the compiling process I also got the error message that the files "flow2d3d.lib" and "flow2d3d_openda.lib" in "src\engines_gpl\flow2d3d\bin\release" coundn't be found. Obviously the libraries of the source code are incompletely compiled, too.

Please tell me, if you had the same problems with compiling the source code and if you know how to solve them. Thanks for any advice!

Hi Benno,

Can you post the contents of the output window inside Visual Studio on this forum: (click in the output window to be sure it has the focus, <ctrl>-a selects everything, <ctrl>-c copies it to the clipboard, open a text editor, <ctrl>-v will paste everything in here, safe this as a text file and attach this file to a new post.)

Thanks a lot Adri for the reply! I'll post it right away.
