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!

Windows Compile

Hi,
How important is it to compile with the recommended versions of VS and ifort? I'm really having trouble getting hold of VS2008, all links lead to VS2010! - can I somehow use the express versions of VS (Intel Fortran 11.0 won't install easily with the express version of VS)?
I've seen a couple of posts referring to VS2010, Ifort12 - if I go down this path can I be sure that the program will execute correctly on a successfull build, or can there be problems running the program?
Thanks, Ben

Hi Ben,

I use VS2010 with Intel12.0 Fortran compiler myself. I did not run into any problem related to these versions yet. But I must admit I did not run the complete testbench yet.
If you want to be absolutely sure that the resulting executable is as close as possible to a fully tested version, you should stick to VS2008/Intel11.0/tagged version. Else go ahead with VS2010/Intel12.0/trunk head.

We have the intention to switch to VS2010/Intel12.0(/64bit) but I have no idea when this will actually happen.

Regards,

Adri

Hi Ben,

Microsoft VS2010 Express is according to Intel not sufficient for integrating the Intel Fortran compiler, s.

The article is from 2009 and I have not tried it on my own.
