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.

Storm surge modeling - inundation

Youngling Posts: 10 Join Date: 10/18/13 Recent Posts

I am working on a model for a study project. I am fairly new to Delft3D and I have this general question. I use Delft3D and sometimes DelftDashboard for the set-up of a flow calculation. Since I have my own bathymetry I don't use DelftDashboard for that, but I still would like to incorporate some convenient features of it.

I want to set up a storm surge model, where I can run the model and eventually see how much of the land gets inundated.
How do I do that? What type of calculation do I do? And how do I change the results of waterlevels to inundation? Is that possible with QUICKPLOT or do I need another tool?

Hi Robert,

All information you need was presented during the "Delft Software Days" (28 October - 8 November). It's a pitty you missed that.

May be the webinar "8. Tsunami simulations using Delft Dashboard and Delft3D" can help you going.
