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!

Make install mpi.mod error

Hi,

I recently checked out the stable Delft3D version 5.01.00.2163 under the tags subdirectory. I got through the configure step but when I ran the following make ds-install, I received the following error:

use mpi
1
Fatal Error: Can't open module file 'mpi.mod' for reading at (1): No such file or directory

The Linux distribution of the server is Ubuntu. Any suggestions?

Thanks,

Hi Drew,

Yes, compiling with mpi on Linux can be painful. This error suggests that the mpich2 include file "mpi.mod" can not be found. Something like the following command:
export MPI_INCLUDE=/opt/mpich2-1.4.1-gcc-4.6.2/include

must be executed before executing the "make ds-install". See the mpich2 part in "https://svn.oss.deltares.nl/repos/delft3d/trunk/src/build.sh".

But, this should not be needed explicitly when you compiled mpich2 correctly in the default directory. Please read this FAQ item carefully.

Regards,

Adri
