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!

CSV file export

Youngling Posts: 2 Join Date: 9/18/16 Recent Posts
Hello everyone, i have been using Delft3D for quite a few days. As part of my work i have to export csv files from history file for each of my observed station. I have almost 150 observed station for which i have to manually select 150 stations individually at a time. It takes a lot of time. Is there any simpler command so that i can export all the stations at a time or i can select all the stations at a whilw for the purpose of export. Any suggestion would be highly appreciable. Thanks in advance.

Hi Mostofa,

You have 4 options:
1. Use QuickPlot
It contains an "export to csv file" option. You can record/create your own macro file to do multiple actions in one go.
2. Use MatLab
QuickPlot is written in Matlab. You can execute QuickPlot commands in your self written Matlab script.
2. Use VSI (Delft3D Utilities)
This is a GUI to view output files. It contains an "export to csv file" option.
3. Use ViewSel (Delft3D Utilities)
This is the command line version of VSI. You can write your own batch file to extract data from a nefis file into an ASCII file. A manual is available here.

Regards,

Adri
