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! 

 

=======================================================
We have launched a new website (still under construction so expect continuous improvements) and a new forum dedicated to Delft3D Flexible Mesh.

Please follow this link to the new forum:

Version numbering

Hi, I read the remark about version numbering on the 'Source code' page, but I still don't understand what the difference is between tags that look way different, e.g.,
5.01.00.2163/
5169/

and whether I should prefer one over the other.
Thanks!

Hi Moritz,

The key identifier is the "revision number". Every time that the source code is updated, the revision number is increased. The revision number is the unique identifier for a specific version of the source code.

"5.01.00.2163" is the full Delft3D-FLOW version number, where "2163" is the revision number.

Since revision number 2367, The Delft3D source code also contains the DELWAQ source code. That's why we decided to remove the Delft3D-FLOW specific part and only use the revision number to identify the source code. Revision number 5169 contains:
DELWAQ Version 5.03.00.5169
PART Version 3.78.00.5169
Delft3D-FLOW Version 6.01.16.5169
Delft3D-WAVE Version 3.04.02.5169

You can find this information in the SVN log history of each tagged version.


Hope this clarifies it a bit.

Regards,

Adri
