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!

Delft3D-WAVE invalid gridfile error

Delft3D-WAVE invalid gridfile error

Hello,

The Delft3D GUI gives an invalid gridfile error when importing the attached grid. I've edited it to change the missing values to 0, and it appears fine in the visualization of the gui.

I have tried various things to fix the error, with the only success if I change the coordinates of the grid entirely. This grid is nested within a larger model and all the other grids work and produce wave outputs except this one.

I would appreciate some help in identifying the specific issue with this grid and Delft3D-WAVE, as it works as intended within FLOW.

Many thanks,

Will

While the gui still gives an error for this grid, I managed to find another error in my input and it now seems to work fine despite the gui error.

As a further question I am curious as to whether vegetation has been added to the Delft3d-WAVE module, as I have it included in my FLOW model and would like to run both with online coupling.
