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!

Executable file not found (d_hydro.exe)

When i start a calculation in Flow, the massage "Executable d_hydro.exe not found on directory C:/Program Files/Deltares/Delft3D 4.02.02/win64/flow2d3d/bin" appears. What is wrong?

Hi Denis,

After downloading and installing the GraphicalUserInterface, you still have to compile the kernels yourself. Please follow the instructions on this page.

If you don't want to compile the kernels yourself, you can buy a service package.

How does one go about compiling the kernels , can you give me a walk through please ?

Hi Rushawn,

Compiling instructions are on this page.

Hello Adri,

 

I am having the same error message as the people above. I found that I do have the d_hydro.exe but it is not in the c: drive (this is because I am using an university computer and need permission to access the c: drive).

Will the computations work if I simply move the folder from the current E: drive to the C: drive? Please advise!

 

Thank you,

 

Gabriel
