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.

Compilation - VS won't copy wave.exe

Compilation - VS won't copy wave.exe

Youngling Posts: 2 Join Date: 7/27/17 Recent Posts

Hello  everyone,


I am currently trying to compile Delft3D (tag: Delft3D_FM_62926)


i was able to do it for every solution, apart from the wave one.


I keep getting the error "wave_exe : error PRJ0019: A tool returned an error code".


Apparently the compiler doesn't know wether  "...\bin\x64\dwaves\bin\wave.exe"  is a folder or a file and can't copy the wave.exe to the directory.


Log message:

"Ist das Ziel C:\Delft3D\Repository\Delft3D_FM_62926\src\bin\x64\dwaves\bin\wave.exe ein Dateiname
oder ein Verzeichnisname"



I followed the instructions on this thread "".

I deleted the destination folder, changed the Delft3D folder to C:\Delft, tried to manually copy the wave.exe to the destination folder.


None of the above solved my problem.

The complete log follows attached.


Any light on this?


Best regards,
