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 Errors(LNK1319 and LNK1169). Windows 7, 64-bit

Hi All,

I am getting a few errors when I try to compile the tag 5.00.09.1882, does anybody know how to fix these? I've altered the hard coded fortran compiler in several files to refer to "IFORT_COMPILER13" instead of "IFORT_COMPILER12", and I did "update" the project from Visual Studio2010 to Visual Studio 2012, but other than that I've made no changes to the code. I did Any help is appreciated.

Windows 7
64 bit
Visual Studio 2012
Intel Fortran Compiler 13


Here are the errors, and I'm attaching the full build output as well.



42>../../bin/Debug\mormerge.exe : fatal error LNK1319: 1 mismatches detected

41>bin/Debug\02-streamtest.exe : fatal error LNK1319: 1 mismatches detected

thanks!

Hi,

Looks like a link problem with these tools.
VS2012+Intel13 is not supported yet.

Anyone having the same experience with it?

Regards,

Adri

Thanks Adri, your emailed suggestion to switch to VS2010/Intel12 led to a fix.

I got a good build by switching back to VS2010 and then switching from Microsoft .NET 4.5 back to .NET 4.0. So this is a good configuration on my machine:

Windows 7 64-bit
VS2010 with MSoft .NET 4.0
Intel Fortran 13 (need to change hard coded references to version 12)

The switch in .NET version, by the way, was to correct errors like this one, which popped up after I switched back to VS2010. They went away as soon as I switched to .NET 4.5

Hi Christopher,

This is solved in revision 1980: "d_hydro_open_source_vs2010_intel13.sln" compiles without problems, both in VS2010 and VS2012.

Regards,

Adri
