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!

Hi Adri,
After successfully compiling, I ran the example 01_standard but it is unsuccessful. An error would be appeared in DOS window.

-------------------------------------------
Executing " mydir/Delft3D/bin/win32/flow2d3d/bin/d_hydro.exe TMP_config_flow2d3d_5124.xlm" ...
d_hydro ABOUT: Cannot load component library "flow2d3d.dll". Return code: 127

ERROR: child process exited abnormally
- Starting "d_hydro.exe" may give more information:
- Run "deltares_hydro.exe <INI-inputfile> -keepXML".
- Run "d_hydro.exe TMP_config_flow2d3d_<processId>.xml.
-------------------------------------------

I read the comments in the Frequently Asked Questions about running a calculation part whit title of " On Windows, the message 'Cannot load component library "flow2d3d.dll"' appears" and checked the run_flow2d3d.bat file. everything was ok. then i started d_hydro.exe directly following the instruction the new error appeared as :
"The procedure entry point for_array_copy_in could be located in the dynamic link library libifcoremd.dll."
Please give me a way for this error.

Many thanks and best regards,

Hi Ali,

Maybe you have set the addtional lib path in your visual studio.

libifcoremd.dll is a lib(dll) located in the fortran compiler's folder. Search this file and check if the path is in your addtional lib settings.

Success,

Hi, Qinghua,

I faced the same problem when running the standard example on a win 7 32 system.

I checked the environment setting, the $(ifort_compiler11)\lib\ia32 is set to the environtal parameter 'Path'. And in the project 'flow2d3d', the former lib folder aslo in the additional library directories. However, this problem still exists. I tried dubugging the d_hydro project, it works successfully. when changed to the release running, it failed. What's the reason?

Hi Xiaoli,

If it works with debug version, but not with release version, it most probably happens because the libs are messed up. You need to have a clean check out and compile the code in release again. That should work.

Cheers,

Hi, Qinghua,

I tried the old version 4.00 on the system 32, it works. The formerly used version 5.09 doesn't, it seems some error occures when searching the executive file address.

Dear Xiaoli,

Yes, it is possible. The file structures have been changed from 4 to 5, then to 6 due to the update of the system and it is getting more and more complex.

Pls refer to the examples attached with the source code, where there are batch files to run the examples. You just need to adjust your own batch according to those example batch files.

Regards,


Qinghua
