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!

Wind Input for SWAN

Youngling Posts: 3 Join Date: 2/9/17 Recent Posts
Hello All,

I am posting about generating a file for wind data in SWAN. For this question, I'm concerned about winds that are not varying in time, just supplying winds in a grid format to my domain. From my understanding with reading the manual, the winds can be given as a single grid file with U grid given first and then V grid given second in the file. Is this correct? I see that winds can also be given as separate U and V grids. Is one method superior? Or is it user preference? I guess my question is am I understanding the way to supply grids correctly in that they need to be supplied in a similar format to a .bot file, both syntax and file format? Also are there any resources or code examples online in python or matlab that I could compare to what I have for generating the wind file? Any help in this area would be greatly appreciated!

Cheers,
Nate
