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!

Delft3D 4.00 license error

Hellow

I use Delft3D Open Source version 4.00.02 in Windows XP computer and it works fine when I use flow or grid sections.

But, when I use WAQ - Waq(1) section, i always get a error message.

The message contents are as follows.


Error: Authorization problem
No such feature exists.
Feature: DHS_Delft3D_WAQ
License path: C:\Program Files (x86)\DS_Flex\Delft3D_GUI.lic;
FLEXnet Licensing error:-5,357
For further information, refer to the FLEXnet Licensing documentation,
available at "www.macrovision.com".



Also, when I click 'Open PLCT -> Define input' button, the error message showes up again.

That massages contents as follows.

"Use of configuratio WAQ is not allowed."



Even if i got a new lisence file, most of tools (related to WAQ) do not work in my computer.

I don't know how to slove this problem.

Would you please help me to solve this problem.


Thank you
Jin

Hello Jin,

Delft3D 4.00.02 is quite old, it came out in 2012. Delft3D WAQ and some tools were not open source yet, which should explain your errors.

I recommend downloading and compiling a newer version of the Delft3D executables. Please note that modern versions of Delft3D are no longer compatible with 32-bit Windows. If your Windows XP version is 32-bit, you may need to upgrade your operating system in order to use the latest Delft3D versions.

In case you do not wish to compile the software yourself, we also offer pre-compiled and validated versions of Delft3D 4 and Delft3D Flexible Mesh in our service packages: https://www.deltares.nl/en/software/delft3d-flexible-mesh-suite/#service-packages


Kind regards,

Sonny de Wit
