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!

vertical velocity profile in 3D simulation

Hi everyone,

 

I have run a 3D hydrodynamic simulation (files attached) but when I plot the vertical velocity profiles it appears like I have two depth layers (one negative, one positive; see attached picture). Can I get help on how to resolve this please. Thanks in advance.

That is a good tip particularly to those fresh to the blogosphere. Short but very accurate info… Many thanks for sharing this one. A must read post!

It’s very easy to find out any matter on web as compared to textbooks, as I found this piece of writing on this site.
