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.

? problem while Installing GISVIEW module of Delft3D

? problem while Installing GISVIEW module of Delft3D

As I've understood, GISVIEW module is a part of common Delft3D installation. A have installed ArcMap as a part of ArcGIS 10.4 suite, and after installing Delft3D GISVIEW plugin must be integrated into ArcMap and new toolbars must appear in ArcMap window with all functionality of data exchange between ArcMap and Delft3D, incluging exporting shape-files to land-boundary files, as it described in manuals.

I've installed Delft3D, but can not see any changes in ArcMap window - there are no new toolbars, new formats for exporting shape-files - nothing.

How can i decide this problem?
