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.

GISVIEW - getting started, incomplete toolbar

Youngling Posts: 1 Join Date: 10/29/15 Recent Posts
I can't get the GISViewer to work properly.

I followed the instructions as follows:
1.) The place of Delft3D is at: "c:\Deltares\Delft3D 4.01.01.rc.03\win32\plugins"
2.) I went to "c:\Deltares\Delft3D 4.0.01.rc.03\win32\plugins\bin" and ran "Register_Arcgis10_MFE_win64.bat"
3) I started ArcMap 10.1 and rightclicked on the top window and put an check in" Delft3D - GISPlugins"

The problem: A little frame for the GisView. - Toolbar appears but without any content.

The reason for the Problem? And better yet: the solution?

Thanks in advance for anyone who is trying to help me!
