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!

error in computing the flow "d_hydro.exe" file

error in computing the flow "d_hydro.exe" file

I get the error below when I try to simulate my single domain flow. My "d_hydro.exe" file also doesn't work. Can someone explain me what could be causing such error or is such error caused because of my faulty "d_hydro.exe" file. I was able to run the models earlier but its only showing this error now. I tried running the previous flow simulation again and it still shows this error. So I am quite sure the error is not in my MDF file.
If anyone could give me an insight to it? would be great.
Thanks!
