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.

Delft-3D Flow, Linux, Ubuntu | how to completely UNinstall

Hello world!

I wish to fully uninstall my current Delft3D suite and repeat the process from scratch.

My distro is Ubuntu Precise Pangolin. The info in the Installation Manual briefly refers to a Red Hat distribution only ('rpm -e Delft3D')
  • I was thinking of a 'sudo apt-get purge <path>/d_hydro.exe'. Is there a(nother) way to do this that you would recommend?
  • Could you also mention if the proposed solution would also be applicable to D-Flow FM as the need arises? (Two pigeons with one stone...)

Thanks a lot in advance for dealing with this.

Sorted! For future reference and corrections/integrations at any time, I did the following

  • Go the directory containing the configuration files (<path>/src/)
  • Run
    make uninstall
  • Run
    make clean

According to The GNU Make Manual the aim of item 2 is
to delete all installed files -- the copies that 'install' and 'install-*' targets create.

The aim of item 3 is
to delete all the files that are normally created by running 'make'.

Therefore I chose to run both actions by undoing the sequence 'make' and 'make install' in reverse order upon using 'sudo' rights. The directories /usr/local/bin were effectively cleared of the Delft3D executables. I missed out checking the content of /usr/local/lib before taking action, but I assume it worked equally well.

As far as I can see, this procedure is independent of the Linux distribution, so it seems to be more general that the one currently suggested in the Delft3D - Installation Manual v1.0, which is specific to the Red Hat distro (Section 4.6).
Subject to the developers' sanity and laugh checks, a distro-independent procedure like this might possibly be included in the manual.
