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 Delft3D on Mac OSX

Hey All,

I ran into an in explicable error when I go to make d3d. I am trying to compile the latest tag on Yosemite 10.10.14. I have all the perquisites installed (following README chapter on compiling with OSX) and I got passed the configuring steps. Here's what I did:

cd delft3drepositorysrc
autoreconf -i
...
./configure --prefix=$(PWD)/build
...
make
...
libtool: link: g++ -dynamiclib -Wl,-undefined -Wl,dynamic_lookup -o .libs/libNefisSO.0.dylib .libs/c2c.o .libs/df.o .libs/er.o .libs/f2c.o .libs/gp.o .libs/gt.o .libs/hs.o .libs/nefis_version.o .libs/oc.o .libs/pt.o .libs/rt.o .libs/wl-xdr.o -lexpat -lstdc++ -L/opt/local/lib -lnetcdff -g -O2 -install_name /Users/swami/delft3drepo/d3d-5275/src/build/lib/libNefisSO.0.dylib -compatibility_version 1 -current_version 1.0 -Wl,-single_module

I spent some time searching around, but I dont think anyone has come across this error in the forums. I also searched around the interweb, but couldnt really get a handle on how to solve this problem myself. Any help would be much appreciated. Thanks!

Hi,

I have the same problem. Have you found a solution?
