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! 

 

=======================================================
We have launched a new website (still under construction so expect continuous improvements) and a new forum dedicated to Delft3D Flexible Mesh.

Please follow this link to the new forum: 
/web/delft3dfm/forum

Post your questions, issues, suggestions, difficulties related to our Delft3D Flexible Mesh Suite on the new forum.

I think the best way to learn the powerful software is study examples which based on the current software...so the question is: are there any demos for learning?

emoticon...sure....emoticon

u vil get tutorial with the set-up which includes all type of examples which r very interesting and helpful
plz run the examples as explained in the user manuals

u can also go through http://oss.deltares.nl/web/opendelft3d/screen-casts for better understanding of the software

happy modelling
regards

Complete open source model input sets are stored under version control and provided through OpenEarthModels. These include delft3d inputs.
A nice example is the 3D baroclinic model incl fine sediments of Patos Lagoon in the south of Brazil:

This model has been created for a publication in Continental Shelf Research:
