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 running example_01 in ubuntu 12.01 32bits

Hello,

I'm newbbie to Delft and I've been folllowing this forum for quite a while to compile the Delft3d under linux (ubuntu 12.01, 32 bits). Finally I've managed to compile it, but I have the exact same problem James is reporting here:
http://oss.deltares.nl/web/delft3d/general/-/message_boards/view_message/217864, so I can't run example 01.

It shows an error:
"d_hydro.exe: oc.c:159: create_nefis_files: Assertion `(BUInt8) -1 == (size_t)(BUInt8) -1' failed."

Adri posted it was a bug on the version that needed to be solved (dec-12).

I'm using tagged version 5.01.00.2163. Was this bug supossed to be fixed? Is the problem already solved? Should I use any other version? any alternatives for linux 32 bits?

This forum is a great support, thank you for sharing your knowledge.

Hi Gonzalo,

I tried it Today with the stable tagged revision 2367: the error still occurs. I will look at this, but not with the highest priority. Can you switch to 64bit?

Regards,

Adri

Hello Adri,

Thank you for your answer. I'll try to switch to ubuntu 64 bits then next week, I guess the procedure for compiling remains the same, doesn't it?

Have a nice weekend,

Hi Gonzalo,

Yes, the procedure is the same.

In case you use the "build.sh" script, please use the flag "-64bit".

Regards,

Adri
