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!

Recently I try to simulate the sediment transport in harbor with delft 3d GUI, the harbor as follows. The menu of initial conditions contains uniform values and initial conditions file, so I try my best to specify a initial conditions file for the sediment transport concertration varying in space with delft 3d-quickin. But I cannot complete it successfully. Could you give me some helps on how to specify the initial conditions file with delft3d-quickin or with some other moduls.




Sincerely thank you in advance

Hi,

You can use Quickin to generate initial conditions generating one file by variables.

When you have generate all your variables, you have to put them into the same file respecting an established order:

- Sea level
- u-current
- v-current
- salt
- temp
- constituent 1 (sediment 1)
....

You can find the method in the FLOW user guide.

Personally I prefer use a matlab program in order to make an interpolation of my variables on the delft3d grid.
If you have several layers, It would be very long to prepare the variables one by one using Quickin.
