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!

Linux: build only FLOW + WAVE

Is it possible to build just FLOW & WAVE in Linux? What is the best way to do that? Can I just move the waq directory where autogen cannot see it?

Thanks

To expand further, the reason is that when I try compiling the latest tagged version, I get the following errors:

../../../../../engines_gpl/waq/packages/delwaq2_lib/src/.libs/libDelwaq2.a(m_sndrcv.o): In function `m_sndrcv_mp_distribute_1d_ldata_on_cardset_':

Googling so far has not helped much. Any help would be much appreciated. I am using Intel v 13.1.1 & OpenMPI compiled with this version of Intel. FLOW & WAVE seems to have compiled nicely... But then I have not been able to test it. Figuring out a way to do that now...

Thanks

Hi Jay,

The easiest way to disable the compilation of waq is by opening file "...\src\engines_gpl\Makefile.am" in a text editor and removing line " waq \".

Your errors are related to compiling with mpi. This is terrible on Linux. The FAQ may help. Or search this forum on related topics.

Regards,

Adri
