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!

Precompiled version

Hello

I have tried to compile the source code so many times without success so finally I gave up and asked for the precompile version for Windows and also for Linux. My question is what is the difference between this precompile version and the one I should have compiled by my own?

Thank you so much for this model

Hi, I read a post by Bert J. stating that open source Delft3D instaler includes pre-compiled binaries of the user interface (GUI), pre and postprocessing tools, but it requires you to compile the Delft3D-FLOW and WAVE executables yourself. There are webinars on how to do it.

Good look,

hey Rafael Thank you for your post, I got the answer below from bert though, I am a little confused since I can not compile the open source even following the webinar.

"Hi Marcelo,

The pre-compiled version is based on the same source code, so there is no difference in functionality.
If you check the version number of the pre-compiled version then you can download the associated source code from the repository (generally one of the tagged versions).

So, the differences are:
We compiled the FLOW, WAVE, etc engines for you.
We verified and tested that those executables work properly together and give results consistent with or improved compared to previous versions.
Include some hours of support depending on the extend of the Service Package.

How can one ask for the pre-compiled version?
