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!

New GUI binaries or Open source version?

Hello,

This question is addressed mainly to Deltares developers.

I am increasingly becoming frustrated with the current software. Is a few (too many) years old and it practically does not run properly on any modern Linux or even Windows system. On linux due to the change of libc and other system libraries rgfgrid and quickin crash at most tasks (on 64bit OS). On windows the situation is a little better although on 64 bit systems on win7 or newer crashes are as good as on Windows

In order to be able to work I am keeping around and old and very slow Windows XP system that will be soon put to rest.

My question is if there is any hope to have a new GUI soon, or at least a developer GUI version. I am concerned about rgfgrid and quickin. The rest can be done from command line so I am not worried about those too much.

In addition this website lists these two programs as being released as open source in 2013. Well, 2013 is almost gone.

Please excuse my tone and frustration, but we really need new binaries or the open source option in order to be efficient (or even, at times, do something).

Thank you,
Bogdan

Bogdan,

I am sorry to read you are increasingly becoming frustrated with the current Delft3D 4 software.

About "if there is any hope to have a new GUI soon, or at least a developer GUI version":

[indent]Yes, there is hope emoticon.

Please find the latest pre-compiled Delft3D 4 graphical user interface (GUI), Delft3D 4.01.00.rc.09 for Windows (delft3d_ohmw_4.01.00.rc.09.zip and other files), on our open source community website (http://oss.deltares.nl/web/delft3d/source-code).

The Delft3D 4.01.00.rc.09 for Windows includes the latest binaries of the RGFGRID and QUICKIN modules.

This temporary extra service is free of charge, as long as the source code of the GUI is not available in open source.

Note that our software development team is working hard on the new Delft3D Flexible Mesh GUI. See also the attached impressions of this new Delft3D GUI, as presented at the Symposium 'Next Generation Hydro Software (NGHS)' during the Delft Software Days 2013 (http://www.delftsoftwaredays.nl/). We expect to release this GUI in open source, later in 2014.

[/indent]

About the modules RGFGRID and QUICKIN being released as open source in 2013:

[indent]2013 is almost gone, indeed.

Going open source with these modules is taking longer than expected. It will be 2014 for sure.

The binaries are available though.

If you would like to receive an advance copy of the source code, please contact me.

If you have any additional questions, please do not hesitate to contact me directly.

Best regards,



Edward Melger
