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!

Installing compiled version of Delft3D (windows) on a different pc

Hi all ,

some time ago i managed to compile and install delft3D on my desktop pc.
Eversince I have been using it without any issues.

Now I want to install the already compiled version on a different pc (my laptop) , but don't manage to do so.

I have all the original compiled folders.
When I copy the files on my external hard disk and run the example 1 I have no issues , when i connect my hard disk to my laptop and try to run the example it says it cant load the flow2d3d file into the library.

Obviously all files are present , because my desktop manages to run the example.
Therefore I think some required software is not installed on my laptop (VS2010 is installed, and i guess i don't need a fortran compiler since the code is compiled already?)

I am gratefull for any help.

Hi Stephan,

You are probably using a version starting with "4.00".

Delft3D-FLOW does need compiler specific dlls. The "4.00" versions assumes these dlls are somewhere on your system and can be used/reached. The "5.00" version tries to collect these dlls and adds them to the install-directory "bin/win32/flow2d3d/lib". Please note that the run script is different for a "5.00" version compared to a "4.00" version.

To solve this, you have two options:
  • Try to collect the needed dlls on the PC where you compiled it. The are probably in a directory named something like "c:\Program Files\Intel\Compiler\11.0\072\fortran\lib\ia32" or "c:\Program Files (x86)\Intel\ComposerXE-2011\compiler\lib\ia32". Copy the dlls into the directory where flow2d3d.dll is located.
  • Use the latest tagged ("5.00") version. Compile and install it. Don't forget to adapt the runscript. See the examples how to do this.


Regards,

Adri
