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 running linux 64bit intel compiler

Hi,

In my previous message I have stated a problem with gfortran 32bit linux. This time I decided to do it with intel fortran 64bit linux. Again single processor worked just fine, but when I tried to run

./run_flow2d3d_parallel.sh config_flow2d3d.ini


i get this error, seems like I stepped further compared to the last gfortran case i had

Any ideas??

Sorry, I made a mistake running the code.

This is actually the output

Hi Veli,

This is probably the same error as in your other post: http://oss.deltares.nl/web/opendelft3d/general/-/message_boards/view_message/113345#_19_message_113345

Regards,

Adri
