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.

Compilation Error(LNK1181 & ERROR while copying)

I am currently trying to compile and build tag However I am left with 6 errors, 474 warnings and 843 messages. The errors are:
  • Error 174 error LNK1181: cannot open input file 'libifcoremt.lib'

    • projects: kubint_intel13, lint_intel13, datsel_intel13, flow2d3d_intel13, flow2d3d_openda_intel13
  • Error 989 ERROR while copying "redist\ia32\compiler\*.dll" to "..\bin\win32\wave\lib"

I am using a Windows 7 machine with Visual Studio 2010 SP1 and Intel Visual Fortran Composer XE.

Any help is appreciated.

error LNK1181: cannot open input file 'libifcoremt.lib'
Solution: For each error, go the the corresponding project. Right click the project->properties->Configuration Properties->Linker->General->Additional Library Directories and change IFORT_COMPILER13 to IFORT_COMPILER14(environment variable name for the Fortran compiler)

ERROR while copying "redist\ia32\compiler\*.dll" to "..\bin\win32\wave\lib"
Solution: Based on this thread:, this error can be left alone as the examples will continue to work
