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!

error on ./run_flow2d3d.sh

Hi - I saw there is some reference to this problem in the compile ubuntu messages, but have not been able to resolve it for myself. It may be related to java?
I built using 4.00.07.0892. Current ifort and gnu compilers. 32-bit.
Any suggestions?

Hi - i re-read the forum
http://oss.deltares.nl/en/web/opendelft3d/general/message_boards/view_message/34610

and tried the suggestion of adding -lmpl to line 78 of common.ma

this seems to have fixed this problem for scientific linux (centros like distribution)
thanks

Chuck
