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!

Recommended stable version for Linux

Recommended stable version for Linux

Hi -

We have compiled delft3d_5.00.06.1677 on our Linux cluster, and appear to be caught (judging from the resulting directory structure and the scripts in the example files) between the XML and INI way of doing things. What would the developers recommend as the version of Delft3D to use that is the most advanced stable version, within which any of the examples could run so long as the code was properly compiled?

Now we have managed to get past the .xml problem but now the code cannot find "libflow2d3d.so". A check of the installation reveals that this file does not exist...

Hi James,

In my opinion, both versions, the stable release (4 times a year) and 'real-time' source code, if you compiled properly, are good. Of course that would depends on the properties of your work.

You are welcome to share your experience here as well!

Regards,

Qinghua YE

BTW, the libflow2d3d.so is the product of compiling. If it is not there, it means the codes are not successfully compiled.

Hello Qinghua -

Thank you for your reply.
