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!

Hi,

I'm a new user of Delft3d. I am trying to run a nested model, but there are errors in the end of nesting.adm file, as follows:

*
* Deltares, NESTHD1 Version 1.60.00.3574, Apr 02 2014, 11:32:53
*
* Run date: 2015/10/10 22:38:42
*
* Name grid file overall model : ######.grd
* Name enclosure file overall model : ######.enc
*
* Name grid file detailed model : C:\Users\..\######.grd
* Name enclosure file detailed model : C:\Users\..\######.enc
* Name bnd. definition file detailed model : C:\Users\..\######.bnd
*
* Name nest administration file : nesting.adm
* Name FLOW observation file : ddtemp.obs //no this file
*


Fatal error detected
Error detected while reading record 6 on grid file detail model
Delft3D-NESTHD1 Aborted

Did you see this before? How to resolve it?

Thanks in advance!

Hi Hardy,

My first guess is that the name of your input files is too long. Can you try with file names with a maximum length of 6 characters in front of the extension?

Regards,

Adri

Hello, I am getting the same error and have tried shortening the name of my files. Do you have any other suggestions?

Hi Ismael,

There is a conflict between the nesthd exe and the grid file.
Use a text editor to remove line 6 in the grid files, holds something about "Missing Value".
With this line removed it should work fine.

Regards,

Emiel
