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! 

 

=======================================================
We have launched a new website (still under construction so expect continuous improvements) and a new forum dedicated to Delft3D Flexible Mesh.

Please follow this link to the new forum:

Hi - I thought Sci. Linux might be close to RedHat. After much problems I un-installed mpich2, downloaded the source from Argonne, and installed to /opt/mpich2 - this seemingly brought me closer to a build of delft3d, but still meet difficulties. I am using the current release of Intel's ifort package. Subversion reports: Checked out revision 1088

Hi Charles,

In revision 477 of the trunk the associated intent(in) clause was removed. Your post indicates that you have checked out revision 1088; however, that doesn't say anything by itself. Which branch did you check out? Did you check out any of the following tagged versions: 4.00.00.0061, 4.00.01.0265, 4.00.02.0423? These tagged versions will give you this problem, but in the other tagged versions this problem should no longer occur.

Hi Bert, I am afraid I am quite new to using subversion. I cut the command from the instructions:

svn checkout https://svn.oss.deltares.nl/repos/delft3d/tags/4.00.02.0423 delft3d_repository

Which tag do I want? this seems the highest number from 4.00.00.0061, 4.00.01.0265, 4.00.02.0423.
I tried:
svn checkout https://svn.oss.deltares.nl/repos/delft3d/tags/4.00.02.0477 delft3d_repository
but the site is down?
"Could not resolve hostname `svn.oss.deltares.nl': Host not found (https://svn.oss.deltares.nl)"
anyway, I will try later.

thanks

Chuck

Hi Bert, svn gave me a hint with try "update" and I found a reference to 4.00.07.0892 which I have switched to.
Now I am at the svml problem. The Makefile does have a -lsvml in it as is:
FLIBS = -L/opt/intel/composer_xe_2011_sp1.7.256/compiler/lib/ia32 -L/opt/intel/composer_xe_2011_sp1.7.256/mkl/lib/ia32 -L/opt/intel/composer_xe_2011_sp1.7.256/compiler/lib/ia32/ -L/opt/intel/composer_xe_2011_sp1.7.256/mkl/lib/ia32/ -L/usr/lib/gcc/i686-redhat-linux/4.4.5/ -L/usr/lib/gcc/i686-redhat-linux/4.4.5/../../../ -L/lib/ -L/usr/lib -lifport -lifcore -limf -lsvml -lm -lipgo -lirc -lirc_s -ldl

I found libsvml.so and libsvml.a in /opt/intel/composer_xe_2011_sp1.7.256/compiler/lib/ia32/

You also mentioned not compiling datsel as a possible solution. That is done by removing the 8 lines in configure.am?

here is the error:

arghh, I can't read. Made suggested changes and Build finished!
thanks
