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!

Definition of the Water Reference Level

Greetings

At this moment I'm seting up my application, and i have a little problem, when I try to define the Water Level in the initial condition window of the Delft 3d GUI, it shows me an error:
invalid reference level [-1000 1000] when i write 2258.72m, which is my water reference value.

The extreme values for my bathymetry are 2224.27m and 2266.92m. So, how is the reference value should be defined?

Any feedback would be very helpful.

Thanks in advance for your time and answer.

Hi Gabriel,

Do you mean your bathymetry is between 2224.27m and 2266.92m?

dear Gabriel,

Then you could define that in your bathymetry file and then the water level is only a few meters, do you?

For example, you just define your reference level at 2224.27m and your bathymetry value is from 0 to 42.65m. Never mind that big number then.

Hope this help a bit?

Regards,

Qinghua
