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!

Compiling on Windows

Hello everyone,

I tried to compile the code today using Visual Studio 2010 and Intel Visual Fortran Composer 2011. At the end of the compilation, it mentioned that the build failed, and I have Build: 72 succeeded, 13 failed, 0 up-to-date, 0 skipped. Is this normal?

I am using the tagged version 3058 for the code.

2. Next I tried to run the examples (run_flow2d3d.bat". The simulation then run and look fine. the guide mentioned that once the simulation is completed, the output files will be produced in the same folder. I am not sure which one is the output file. Does it contain the result of the simulation? what is the format of the output file?


Any help on this matter is great appreciated

Hi Anas,

No, that's not normal. "0 failed" is normal. But if you are lucky the failed part is not related to the main executables.

All files that were not present in the example directory before the calculation and are present at the end of the calculation are output files. The key files are:
  • tri-diag.<runid> This is an ASCII diagnosis file, reporting errors/warnings, run time, version info etcetera.
  • trim-<runid>.def and trim-<runid>.dat files in the (Deltares defined) nefis format. They contain results of the full modelled domain at specified time points. You can inspect them using QuickPlot.
  • trih-<runid>.def and trih-<runid>.dat files in the (Deltares defined) nefis format. They contain results of specified observation points. You can inspect them using QuickPlot.


See the manuals for more information.

Regards,

Adri

Hi Anas,

To solve the errors:
I expect that you need to install service pack 1 of VisualStudio 2010. See this forum.

Adri
