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 Debian Wheezy (7.3 Intel64)

Compiling on Debian Wheezy (7.3 Intel64)

I have a new computer with Debian Wheezy so I need to move delft3d . I downloaded (via svn) delft3d both tag version 3351 and trunk.
I modified some lines of the build.sh in order to use the right tools paths. I am getting this error:

/usr/bin/ld: /opt/mpich2-1.5/lib/libmpich.a(allreduce.o): relocation R_X86_64_32 against `MPIR_ThreadInfo' can not be used when making a shared object; recompile with -fPIC
/opt/mpich2-1.5/lib/libmpich.a: could not read symbols: Bad value


I am using ifort 14.01 and I have tried various mpich2 versions, all compiled with the same ifort but it has not been possible to go forward.
Any help is welcome,

Fermin.

P.S. I have attached build.sh, configure.log and make.log

Hi Fermin,

This should help: recompile mpich with the flag -fPIC added.

Regards,

Adri

I did it. It compiled without errors but I got this runtime error:

d_hydro.exe: symbol lookup error: ~/delft3d/trunk/src/lib/libflow2d3d.so: undefined symbol: MPI_Init

I compiled using this example in the forum and it worked fine!

Thanks a lot to Emark Stanton and Adri.

Hi Fermin,

I expect that running a model without using parallel will work.

It seems that although the compilation succeeded, mpi is not in the resulting binaries. See the FAQ.

Exactly as you expected, trying to run it in parallel mode gave me this result:

Part IV - Reading complete MD-file...
application called MPI_Abort(MPI_COMM_WORLD, 1) - process 1
