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!

parallel computation with flow-wave coupling

Hello there!

I am stepping into the parallel computing world with Delft3D and was wondering if it is possible to run a flow-wave simulation, online coupled, using mpiexe.

Thank you!

Hi, Guilherme,

Welcome to the world of Delft3D!

As the parallelization of Delft3D, refer to the file in the open source folder: .\src\engines_gpl\flow2d3d\doc\parallel_status.txt, where states those features supported in parallelization and those not.

I think wave(swan) is parallized, flow is parallized, but the online wave-flow probably not.

Hope this help a bit!
