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 fortran compiler

intel fortran compiler

I downloaded the source code and want to compile it. However, I have a question about the intel fortran compiler since I don't know which to take. At the moment I use VS2010 (which can be upgraded to VS2012). At the website of Deltares I saw that I need the intel fortran compiler 11.0 or 12.0. At the website of intel ( they show me the products they have, but the version of the fortran compiler is unclear.

So my question is: which one should I take? And are there other options than you can see in the link I posted above?

Thank you!

Hi Annette,

Yes, Intel's site is horrible and contains circular references. They also introduced terrible product names.

I use Intel 12.1 in VS2010. The official name of Intel 12.1 is:
Intel(R) Visual Fortran Composer XE 2011 Update 11, 12.1.3534.2010

Looking at their site, you can only order the newer version "Intel(R) Visual Fortran Composer XE 2013". Intel says it works in VS2010.

So you have the following options:
  • Ask Intel for the 2011 version.
  • Buy the 2013 version.
  • Switch to VS2012 and use the 2013 version.

I know that VS2010+Intel2013 is used by others. I tested VS2012+Intel2013 myself.
