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 space varying boundary conditions in spherical coordinates

Delft3D-Wave space varying boundary conditions in spherical coordinates

Padawan Posts: 25 Join Date: 3/25/12 Recent Posts

I am using Delft3D wave and I would like to set space varying boundary conditions along a boundary. I adopted a spherical coordinate system. How can I impose the distance from corners in order to vary the boundary conditions in space? Should I impose a distance in degrees or in meters?

Managed to solve the problem. If I use a spherical grid the conditions along a boundary must be specified with distances in degrees.

Hi Francesco Enrile,

Sure!  Thanks for sharing this as well!
