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 UBUNTU 11.10 Trunk Release 1318

After updating trunk via svn, I recompiled the source getting this error:

Generating version number in the ./deltares_common_version.F90
Done, new version number is: 1318
make all-am
make[7]: se ingresa al directorio «/home/favila/delft3trunk/src/utils_lgpl/deltares_common/packages/deltares_common/src»
gfortran -I../../../../../utils_lgpl/precision/packages/precision/src -g -O2 -fopenmp -ffree-line-length-none -cpp -c -o buffer.o buffer.f90
buffer.f90:36.13:

use precision
1
Error Fatal: Versión de módulo '0' errónea (se esperaba '6) para el fichero 'precision.mod' abierto en (1)
make[7]: *** [buffer.o] Error 1

Any idea?

Thanks in Advance
Fermin Avila.

Hi Fermin,

The ".mod" files that are already present are out of date. Be sure to start compiling in a "clean" directory. To make it clean:
  • Start with an empty directory and check out the source code from SVN again (preferred option).
  • Execute "make distclean" and check that in subdirectory "...src/utils_lgpl/precision/packages/precision/src" all files with extension ".mod" are deleted (alternative option).


Regards,

Adri

One more time, thank you very much Adri,
It worked fine!
