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!

Merging com*.dat file for delf3d flow wave offline coupling

Hai delft community
A quick question>

How to merge the com*.dat files of delft3d flow output from a parallel domain decomposition run??

"ddcouple.exe will do the merging but only for the hydrodynamic part not the com*.dat files"

I need to do the offline coupling with delft3d wave, for that the communication files have to be set from several com*.dat files.

Kindly suggest the best way to merge the com*.dat files.

Thank you so much for this. I was into this issue and tired to   tinker ar https://vidmate.onl/download/ ound to check if its possible but couldnt get it done. Now that i have seen the way you did it, thanks guys
