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 errors

Hi Michel, I've tried to compile the source with VS 2008 (intel fort 12.0) several tags but I have several errors. It starts in esmfsm and goes down with the rest! deltares_common is produced correctly, I think...

The start of the problem is here:
11>\src\utils_lgpl\esmfsm\packages\esmfsm\src\fsm\fortapi.f90(53): error #7002: Error in opening the compiled module file. Check INCLUDE paths.

The problem is esmfsm can't find the precision definition from the deltares_common.lib (I guess), and esmfsm is used by most of the other projects, so thats why the other projects fail

any suggestions?
