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.

QUICKPLOT and Delftdashboard Error

Youngling Posts: 1 Join Date: 1/17/20 Recent Posts
Hi, i have some problems regarding opening the quickplot and delftdashboard.
I've installed the following requirements:
1. MCR 7.11 for quickplot
2. MCR 8.2 for delftdashboard

But when i tried opening quickplot, it only shows the menu of "Please wait, Quickplot is loading" and it doesn't direct me to the quickplot menu. Same goes to delftdashboard, it says that "Undefined function or variable 'matlabrc'".
Does anyone have these kind of problems?
