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!

Hello all,

Hope you are staying safe and healthy.

I have modeled sedimentation process of rivers flowing into the lagoon. Now, I know there is high amount of total transport rate in some cross sections. In my thesis, I must consider some strategies to overcome the problems related to the extremely high level of sedimentation in my model, and I do not know how can I use Delft3D in order to fix this problem. I wanted to know that is there any strategy that Delft3D can propose such as sedimentation traps, using multi-channel instead of one channel, creating deviation of the channel for input sediments, and so on. Thank you for your time and help in advance.

Sincerely,

Farshad
