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.

Unable to run DelftDashboard batch file

Unable to run DelftDashboard batch file

I have two question, i really appreciate your help.

1. I was able to generate all the files required, but was unable to run the batch file. The batch file shows up and disappears. My computer is window 7 with 64-bit. Please help me.
2. What about if I generate all the files for Delft3D-Flow in Dashboard and bring back in Delft3D. I am thinking opening a new MDF file in Delft and bring all the Dashboard files; especially I want to use the track and tsunami initial condition files, is this possible?

Hai Lema,

I had the same problem. Delft Dashboard (DDemoticon is using flow version 5.00. So you need to save your mdf file to version 5.00.

If, you do not have the option to save the mdf file to version 5.00, then follow the instruction given in the link below:

Hi Abnet and Anas,

Example batch files that fit to the version number used can be found in the examples directory when downloading the source code.

A model being defined by an mdf-file and the files it refers to can be run with the 4.00, 5.00 and 6.00 Delft3D-FLOW versions. The only difference is the way to start it. See the release notes for more info.
