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!

can't get a complete run in Linux

Hi all,

I have the open source version compiled and examples running on Linux. All my configuration files I make through the open source GUI running on VMFusion with Windows 7. I'm trying to do my own run, and, to my knowledge, have all of the setup files that I need. When executing ./runflow2d3d.sh in my Linux shell, I get the following command line output:


--------------------------------------------------------------------------------
Deltares, Delft3D-FLOW Version 4.00.07.1252, Apr 10 2012, 18:24:25
libflow2d3d.so entry RUNME
--------------------------------------------------------------------------------

Part I - Initialisation Time Dep. Data module...
runid : guam
Part II - Creating intermediate files...
Part III - Initialisation of the Execution module...
Part IV - Reading complete MD-file...
Part V - Initialisation & checking input...
Part VI - Initialisation & checking second part...

and then it just stops. The example runs have a Part VII and Part VIII in the command line, followed by many lines giving the status of the run.

Does anyone have an idea as to what I am missing? I wouldn't think my platform switch would be a problem, since all the configuration files are ASCII, but perhaps I am wrong.
Thank you in advance!

Not quite clear,
Did you say:
1) that the example files are running, but that when you try running models created on a different build they don't run?
2) Or do you mean that you compiled the binaries on one machine then moved them to another machine and the models wont run there?

If 1, what version of D3D did you create you model files?

"1) that the example files are running, but that when you try running models created on a different build they don't run?"

This is the case. I'm creating the files on D3D with the GUI on windows, moving them to a Linux machine and running them on the Linux version of D3D there (where the examples work). I'm using version 4 on both machines. I've converted the windows text files to Linux text files using the fromdos command in the Linux shell, but this did not resolve the issue.

It is very strange to me, its runs Part 1-Part VI, then just stops. No error messages or anything.

Turns out the problem was in the .mdf file, which I discovered by picking through the diag file.
