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 compiling Red Hat 64bits - make[5]: *** [libtrisim.la] Error 1

Hi,

I'm trying to compile Delft3D in Red Hat EL 6.0 64bit, however to no avail.
I'm having the following problem:

ld: ../../../../../utils_lgpl/meteo/packages/meteo/src/libmeteo.a(meteo_data.o): relocation R_X86_64_32 against `meteo_data_mp_meteomessage_' can not be used when making a shared object; recompile with -fPIC
../../../../../utils_lgpl/meteo/packages/meteo/src/libmeteo.a: could not read symbols: Bad value
make[5]: *** [libtrisim.la] Error 1

Could anyone help me.

thank you

Hi Henrique,

It looks like you should add the -fPIC option to you compile script.
In version 5.00.00.1234 the build.sh script already has this in all flags.
What version/compiler are you using?
The "could not read symbols" error is sometimes connected with trying to compile 32bit on a 64bit setup. Are you passing the -64bit flag to build.sh?

João.

Hi João,

I have used a version Delft3D "trunk" latest.
The compiler:
- Ifort 11.1

A machine is 64bit.

Regards

Luís
