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!

PETSc on Windows

Hi,

The PETSc library is used as an optional solver in D-Flow FM. Unfortunately it is only available on Linux. Is there somebody who can deliver the Microsoft Visual Studio project file(s) and needed code changes to build PETSc on Windows?

Please help us to improve D-Flow FM.

Thanks.

Adri

Hi Adri,

I am not a windows person and since SciNet at University of Toronto, where I run my parallel secnarios accepts only UNIX/Linux I use Windows only for running DeltaShell and configuring things. Even that is not perfect, for example generating the parallel MDU files is faulty in the GUI (I opened a BUG report in the Delta Shell forum since a formal bug reporting tool is not available or I am not aware of it), but works fine with
generate_parallel_mdu.sh
provided in the "bin" directory on Linux.

However, I found this note but requires using Cygwin for compiling it, which may come together with some performance hits.
