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!

How to create dep file from txt file?

Hi all,

I'm newbie in Delft3D. I want to know how to make delft3D dep file from txt file? The txt file is contained of X Y Z coordinates. I tried to start my model by making grid 10 km x 10 km and I intend to import the bathymetry (*.txt) as Sample file, but It didn't work. Is somebody know how to start modeling from measurement data? Thank in advance for your help.

Regards,
Fajar

change the ".txt" extension into ".xyz", then using Delft-Quickin, open this bathymetry sample with extension .xyz and start inetrpolation..

Hope this helps

Hi Emiterio, thank you for your suggestion. I tried it, it work well, although a message came up ("Number of double points removed: xxxx") but I think it's not a problem. Thank you very much.
