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!

managing multiple D3D installs

Hi,
I am wondering the best technique to manage multiple D3D installs on the same machine. I often like to test models using different executables but it seems without re-installing each time I cannot get things to work. I have written batch files to change all the path and define "D3D_HOME" and "ARCH" and the like but it seems there are more paths/environmental variables or other hard coded things I am missing. Also it doesn't seem you can have two menus installed as neither seem to work if you have two D3D versions, I get the error "menu configuration file not found". Ideally I would like to run a quick batch script to tell my machine which version of D3D to use. Is this or something similar possible?

Thanks

Hi Jeff,

Attached is file "d3d_menu.bat" as used in recent versions. Copy it into your Delft3D installation directories (e.g. "c:\Program Files (x86)\Deltares\Delft3D 4.01.00.rc.04\win32"). Executing this script will start the Delft3D-GUI in the related directory with all needed environment settings. Adaptions may be needed when using this for older versions.

Regards,

Adri
