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!

compilation and linking problems....

I am attempting to install delft3d open from a tagged version which I understand is stable. I am using VS2012 and Intel 2017. In the downloaded files was a Python file prepare_sln.py which I understand prepares the solution files for the compiler. That ran OK, however, when I ran the solution files through the compiler it generated over 700 errors, 900 warnings and 55 remarks. Most appear to be of the form "Error 1025 error LNK2001: unresolved external symbol @__security_check_cookie@4 nefis.lib(gp.obj)" so I checked the FAQs and noted that the correct IFORT has to be referenced in the vcproj files. However, this is indeed correct in the files, but clearly these libraries are not being found. The warnings appear to relate to mismatched argument lists....but...first if anyone can help with the first 700 errors that would be excellent! The entire process took over 10 hours which seems a rather long time required to build a modelling system....
