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 running D3D in GUI while scritpts ran succesfully

Hello,
I´ve compiled tag 64381 from delft3d_fm repositor using VS2019 and IVF2019. There were no erros in the compilation but a lot of warnings.
I succesfully ran all examples (flow,wave,etc) using the batch scripts.
Installed the 4.04.01 GUI, copied all the bin files from the x64 folder, but after running the same example (01-standard) receive the following error:"d_hydro ABORT: Cannot load component library "flow2d3d.dll". Return code: 127
child process exited abnormally"Try running the Wave example but receive the following error:Command: run Delft3D-WAVE
   Starting Delft3D-WAVE computation ...
child killed: unknown signalWhile in GUI I can load the mdf and check all the input information.Is this a compilation, run-time error or a compatibility issue (source 64381 mismatch with GUI 4.04.01)?
It is strange that the batch script work but the GUI dont.I´ve tried to prepare the files in the GUI and run from script but the name of the xml file is different config_dflow2d3d.xml vs config_d_hydro.xmlAny help would be greatly appreciated.
