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!

Compiling on Red Hat Linux Enterprise

I am trying to compile Delft3D on a linux redhat enterprise server. I've tried to get all the prerequesites and can successfully run ./autogen.sh and ./configure. When I use the make command I get this error:

Any suggestions? Thanks!

Hi Alejandra,

The small program "version_number.exe" is the first thing being compiled inside the Delft3D source code. When compiling the rest of the code, this "version_number.exe" is immediately used/executed. This execution results in an error. It seems that compiler specific libraries (libimf.so) can not be found.

When using the Intel compiler you should execute the related "ifortvars" script before compiling Delft3D. The related command should look like (depending on the Intel version and the installation directory):
. /opt/intel/Compiler/11.1/072/bin/intel64/ifortvars_intel64.sh intel64

When using the GNU compiler you have to add the library directory to environment parameter LD_LIBRARY_PATH before compiling Delft3D. The related command should look like (depending on the GNU version and the installation directory):
export LD_LIBRARY_PATH=/opt/gcc/4.9.2/lib64:$LD_LIBRARY_PATH

Regards,

Adri

Thank you, I was finally able to compile it.
