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~
I used VS2008+IF11.1 to compile source code 4.00.07.0892 and some codes older than it . I successed all the time. Both WAVE and FLOW can work .But when I used the same tools and same way to compile 5.01.00.2163 or other 5.xx.xx.xxxx I failed. The VS showed that there is no errors ,but when I run WAVE it can not work, the error information is " swan_0472ABCD_....is not exist",while when I run FLOW it does work. I quite doubt about it, I beg for help!

Add~~~When the VS finish compiling the code , I can not find file 'bin' but VS show that there is no error . I also used VS 2012+Intel visual fortran XE 2013 to compile the code ,but VS show that there is 10 errors and I can find file 'bin'.

Hi Green Xiang,

The directory "<yoursourcecode>\bin" will not be created when building the "debug"-version in VisualStudio, only when building the "release"-version.

The location of "swan_0472ABCD_.." in "<yoursourcecode>\bin" is changed. It is now placed in directory "<yoursourcecode>\bin\win32\swan\bin". Script "<yoursourcecode>\examples\03_flow-wave\run_flow2d3d.bat" is adapted for these changes. But if you use another script to start WAVE, you will have to adapt that too.

Regards,

Adri
