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.

Post your questions, issues, suggestions, difficulties related to our Delft3D Flexible Mesh Suite on the new forum.

I am trying to run DelftDashboard and it tells me to install MCRInstaller. I did this and reran Delftdashboard and again it tells me to install and run MCInstaller which I did and it still doesn't work. All files are in the same location.

Hi Jon,

It seems that DelftDashboard isn't able to locate the MATLAB runtime environment.
You indicate that you have run the MCR Installer, but that it still indicates that it can't locate the MCR environment.
I'm not directly involved in the DelftDashboard developments, so I'm not sure which version of the MCR environment they need right now.
For Delft-QUICKPLOT I'm using version v711 of the runtime which is by default installed in

C:\Program Files\MATLAB\MATLAB Compiler Runtime\v711

Please check the version that you have installed and check that the associated bin\win32 folder is on your environment variable "PATH".
For the installation indicated above the folder included in the environment PATH should thus be:

C:\Program Files\MATLAB\MATLAB Compiler Runtime\v711\bin\win32\

Generally the MCR Installer works fine, but sometimes for some reason it doesn't add the folder to the PATH automatically.

Does this solve this problem?
