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!

Delft3D under OSX

hi all,

I am trying to compile Delft3D under OSX 10.7.4. I found this post,

http://oss.deltares.nl/web/opendelft3d/od3dforums/-/message_boards/view_message/22355

in which Fedor mentioned he compiled and succeeded that (perhaps an earlier OSX). Somehow I could not reply to the thread, so I created this new one.

I tried to checkout the branch Fedor mentioned in above post, but it is not there anymore. This is understandable since it has been more than a year. So now I would like if there is a special version for OSX that I should check out? And what is the proper procedure for compilation and installation?

I tried with the standard Deflt3D linux version using the build.sh. After installing some necessary GCC tool and mpich2, the compilation seemed successful. However, as I checked, the binaries were not installed at the proper place (they were installed under Delft3D/sources/src/bin) instead of Delft3D/bin/lnx as it does for Linux. Perhaps this is correct after all? Another issue is that it does not include the folder delft online as mentioned by Fedor. Look like this is wrong version. But I am a bit curious somehow it can be compiled under OSX.

Regards,

Mingshun

Hi Mingshun,

I'm unfamiliar with using bash on OSX.. Can you advise on how to do the compilation steps on mac?
For example, what is the equivalent of sudo apt-get install XX command from linux in OSX?
Also, how does someone use subversion in a mac? Is it the same as linux? Are the gfortran, g++, flex, etc all still needed and acquired in a similar way as in linux?
Sorry for the lame questions.. I don't speak mac emoticon

Thank you,
Shawn

Hi Mingshun,

I'm sorry for this late answer; somehow I missed this thread.

The branch Fedor mentioned is removed because all the updates in that branch are merged into the trunk. There is no special OSX version. Just use the latest tagged version (or the trunk).

For compilation and installation: see chapter "Compiling on OSX" in file "src/README". I expect that the script "build.sh" will not work on OSX: you will have to install all needed tools/libraries properly in the default locations.

Installation in "Delft3D/sources/bin/lnx" is done next to "installation" in "Delft3D/sources/src/bin" by using the command "make ds-install". Again, I'm not sure whether this will work on OSX. Fedor installed it directly into /usr/local.

Regards,

Adri

Does the GUI work on OSX?
