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 ,

How to set Lateral boundary in delft3D wave model ? Could I set periodic boundary as Lateral boundary conditions ?

But how to make it ?

Thanks ?

Dear Chenzhen,

How do you mean 'Lateral boundaries'? There is no difference between for instance the 'offshore boundary' and other boundaries in D3D-Wave with respect to the input procedure. Periodic boundary conditions are not possible. But why would you want to?

Can you explain your setup in somewhat more detail?

Best regards, Peter
