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.

Cannot load component library ""

I compiled and ran the executable successfully in serial mode. However, when I take the entire executable directory and move it to another machine, which has exactly the same architecture as the machine that the code was successfully compiled, I get the error:

d_hydro ABORT: Cannot load component library "": cannot open shared object file: No such file or directory

When I checked the links using ldd d_hydro.exe, I get => (0x00007fffa13ff000) => /lib64/ (0x0000003c5d200000) => /u/home/veeramon/utils/lib/ (0x00007f44742a3000) => /usr/lib64/ (0x0000003c60a00000) => /lib64/ (0x0000003c5de00000) => /lib64/ (0x0000003c5f600000) => /lib64/ (0x0000003c5d600000) => /lib64/ (0x0000003c5ce00000)

I do not see a link to libDelftOnline. How do I solve this issue?

Could you possibly try to check shared library dependencies for Maybe executing ldd will give a clue.

Kind regards,
