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!

How to import .tif file for bathymetry

Hello,

I have the bathymetry of the bay I need to study as a .tif file, how can I convert it in .dep file for DELFT3D? 

Thanks!

Hi Cecilia,

There are a number of ways you can do this. I usually convert the tiff file to XYZ sample data using GIS then interpolate it onto the grid using QUICKIN.

Depending on your preferred GIS software there are many ways to convert the tiff to XYZ. I suggest searching for "tiff to XYZ" or similar. Once converted you should have a text file of comma separated values, where each line in the text file lists the X, Y, and Z coordinates for an individual pixel in your tiff.

Once you have the XYZ samples file it is easy to read it into QUICKIN and interpolate it onto your model grid using the approach described in the tutorial section of the QUICKIN user manual.

Hope that helps.

Richard
