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!

Create bathymetry using Quickin

Youngling Posts: 15 Join Date: 1/20/16 Recent Posts
Hello everyone,
I am new to delft 3D and am very much in need for help. I am unable to find the method used to create the depth file. I have the bathymetry in AutoCAD format. I would like to know how i could convert it to a depth file or how i could use the coordinates to create depth file using quick in.
I would be grateful to anyone who could help. Thanks!

Hi Mathanki,

As I know there is no direct way to import bathy data into d3d quickin as Autocad. what you can do is that you can convert Autocad file into .xyz or .txt file using Autocad or another tool. The .xyz sample files will usually contain X and Y coordinates in m in some Cartesian coordinate system such as UTM (with arbitrary offset) or longitude and latitude coordinates in degrees (WGS84).
Once you have .xyz sample file you can follow Delft3d Quickin manual for your task.

Good luck

Dear Ruchira,
I checked the user manual for the bathymetry format. But am unable to understand the contents of it. It seems like only the depth have been listed?


And on an unrelated note, to create lanboundary of my area of interest, I extracted the poly line coordinates from autoCAD and converted it to be a .ldb file and when i opened it in Delft3D RGFGRID, nothing shows up. Can you give any reasons as to what might have gone wrong?

Thank you!

Hi,
Pls check the coordinate system you used. it should be the same coordinate system for both .ldb file and .dep/.grd or bathy samples you applied. Normally I use UTM.
Also, you can just import your .ldb into RGFGRID if it is not showing anything then better check your .ldb file whether it has the correct format. (Refer quickin user manual page no 79.)

cheers
