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.

Error while compiling tag 2869

I'm trying to compile the latest tag, but I get the following error when I open the VS2010 project
Project "D:\tags\2869\src\engines_gpl\flow2d3d\packages\plugin_3dmortrafrm_c\plugin_3dmortrafrm_c.vcxproj" could not be found.
I've noticed that no folder named "plugin_3dmortrafrm_c" is present in the "tags\2869\src\engines_gpl\flow2d3d\packages\" repository folder.
I have tried to compile anyway, but I get thousands of errors.
Where am I wrong?
PS I have compiled without errors the previous tag and in the meanwhile I have only updated the Fortran compiler

Hi Nicola,

It seems that you are using d_hydro_open_source_vs2010_intel13.sln (for Intel 13 Fortran compiler). That solution indeed needs some updating. We are working on that.

Meanwhile, you have the following options:
  • You can update the solution and related project files yourself. By comparing with the default (Intel 12) solution/projects, you should be able to solve this.
  • Switch to Intel 12 Fortran compiler and use d_hydro_open_source_vs2010.sln
  • Use an older tagged version (this is not my favourite work around). After a first quick investigation, I expect that the last but one tagged version (revision 2703) probably will work fine.

Dear Adri,
you are right: revision 2703 works fine. I'll try to solve the problem following the options 1 and 2.
