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.

I am trying to install Delft3D under Ubuntu. I followed the installation manual, and get stuck in the "build" part:

20111007.112741 :: Running autoreconf -ivf &> logs/autoreconf.log
20111007.112800 :: Running CFLAGS='-O2 ' CXXFLAGS='-O2 ' FFLAGS='-O2 -DWITH_DELFTONLINE ' FCFLAGS='-O2 ' ./configure --prefix=/home/ling/Documents/Delft3D/delft3d_repository/ &> logs/configure.log
20111007.112816 :: Running make ds-install &> logs/make.log
20111007.112817 :: Make fails!

I have installed intel fortran compiler, here is the path:

also, I installed mpich2 with a shared library. I modified the MPILIBS in file as:
MPILBS = /usr/share -lmpichf90 -lmpich -lpthread

Here attached the config.log file FYI.
I know little about Linux. What should I do? Pls help me. Many thanks!

Hi LZ,

This is a known bug. You have to copy (overwriting the precompiled version of) file
and try again.

Mind that you are trying to build a 64bit executable, so you must execute -intel64
