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.

Compiling on windows

I installed Visual Studio Ultimate 2010 and Visual Fortran 12.05. I also installed version of DELFT3D . The result was this : Compile : 53 successfully , 6 failed , 0 upgraded, 0 skipped . Even so, I tried to run the examples , and the four ran very well (standart, domaindecomposition, flow-wave, fluidmud). However I want to know if these 6 failures will cause me problems later ? . I am waiting for a return of the site with the GUI to install it and then test other examples as webinars . They said that the return will be within 5 working days , so I imagine that on Monday or Tuesday I 'll be installing.
The error appears here :

42 > mormerge_vs2010 - 1 error ( s ) , 0 warning ( s )
41 > src \ d_hydro_version.cpp ( 57 ) : warning C4996 : ' strncpy ' : This function or variable may be unsafe . Consider using strncpy_s instead . To disable deprecation , use _CRT_SECURE_NO_WARNINGS . See online help for details .

And then appear such errors : error RC2167 : unrecognized VERSIONINFO field ; BEGIN or comma expected

So, those 6 failed will cause me problems, later?

dear Kyssyanne,

I would not expect big problems later.

The errors you showed are related: 1) Mormerge, 2) a version problem. It will not hamper the computation, I would say, but I still suggest you to have a full compilation. It seems like you missed a sp1 for the fortran compiler. Am I right?

Dear Qinghua,

I installed Microsoft Visual Studio 2010 versão 10.0.40219.1 SP1Rel, with microsoft net framework versão 4.0.30319, and Intel visual fortran composer XE2011 Integration for Microsoft Visual Studio 2010, 12.0.3471.2010. So i need to install another SP1 for fortran compiler, that's is?

Hi Kyssyanne,

No, you don't need an SP1 of the fortran compiler, only for Visual Studio.

If you still have problems with compiling:
  • Do try to run the examples. The problems might be related to tools you don't need.
  • Copy/paste the full contents of the output window inside VisualStudio into a file and attach that to a post here on the forum.
