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!

Batch Flow File Delft Dashboard

Hi!

I am new to Delft3d and Dashboard. I downloaded from the open source. I am running through the Webinar screencast on 'Tsunami simulations using Delft Dashboard and Delft3D' with Deepak Vatvani. Error messages seem to have appeared on my .exe window throughout the set up of the model. The batch file along with all the other files (.mdf, .bca etc) have been produced in my working folder, but when I try to run the Batch file, the window pops up and disappears immediately. I can't get it to run to produce any output files!

Any help/advice would be GREATLY appreciated!!
Best,
Emma

Hi, Emma,

Probably you could start a dos window and run the batch file there. In the dos window, probably it will show more than flashing away.

Hi Quingha,

Many thanks for your repsonse! I have tried running the batch file from a command prompt, by both dragging and dropping into the command window and by locating the batch flow file manually in cmd.
The following error message has appeared;

'c:\delft3d\w32\flow\bin\\deltares_hydro.exe' is not recognised as an internal or external command, operable program or batch file.

However, the batch_file I am trying to run is in a different folder on my desktop.
Should it be in this c: folder? Or is there a program that must be in the same folder as the batch file I am trying to run? Or perhaps is Delft3d not installed properly?

Thanks in advance for any response!
Best,
Emma

Hi Emma,

You should open the Dos windows and change it to the folder where the mdf and other files located.

Maybe there are good examples to show you how to prepare the batch file and ini files. In the source code, you can find a folder called examples, where there are 4 well-prepared examples. If you can run those examples, you should be able to run your own.

Regards,

Qinghua

I am having the same problem...anyone found a resolution to this? I'm trying to work through the saotome tutorial.

I am running delftdashboard through matlab and my version of Delft 3D is 4.00.02

My working directory for delftdashboard is C:\delftdashboard\saotome
My working directory for Delft 3D is C:\Delft3d

I did everything exactly the same as in the tutorial, but when I try to run the batch file (in the command prompt), I get this:

C:\delftdashboard\SaoTome>batch_flow
'\deltares_hydro.exe' is not recognized as an internal or external command, operable program or batch file.

I'm at the end of my rope - someone please help!

Hi Sarah,

DelftDashboard is currently not able to start a calculation using the latest Delft3D version. You can still use DelftDashboard for creating all input files, but then it's easier to use the Delft3D-GUI to execute the calculation. So:
  • Be sure that you can run the example testcases, follow the instruction on this page.
  • Prepare your model input using DelftDashboard.
  • (Optionallyemoticon Check your model input by opening it in the Delft3D-FLOW-GUI.
  • Run your model via Delft3D-GUI


Regards,

Adri
