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.

Intel run-time error with RGFGRID and QUICKIN

Intel run-time error with RGFGRID and QUICKIN

Hi everyone,

I am a new user of Delft3D. Over the last few weeks I have been practising using RGFGRID and FLOW using the tutorials, as well as exploring setting up my own grid for my research project analysing morphological change in the Mahanadi Delta, India. One day last week I went to open RGFGRID and received the following error message:


I thought this could be a problem with licensing for my Intel software but as of yet I'm struggling to resolve it this way. Only RGFGRID and QUICKIN are effected as far as I can tell.

Any advice as to what the problem could be? I am using windows 7 64 bit, Visual Studio 2010 and Intel Parallel Studio XE 2015 with Fortran compiler.

Kind regards, Sarah
