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!

Capabilities of Delft3D

Dear Sir,
I have some questions about the capabilities of the Delft-3D.

I'm targeting Gulf of Suez to be simulated by Delft-3D including heat flux model (ocean model). We are using outputs of 12-km from our developed atmospheric model (ReGCM4). The bathymetry is attached.

I have some questions:
Is it a must to use Non-Hydrostatic conditions? My supervisor states that "I think it would be better to use a non-hydrostatic model for this work. First, your resolution of the ocean model is very high, ~1 km, so you resolve non-hydrostatic processes. Second, you study the outflow to the Red Sea."

Second comments:
What are the important outputs of the Heat flux model integrated in Delft-3D?
We tried and we got evaporation in summer more than winter. Recent studies suggest the evaporation over the Red Sea and the Gulf of Eilat is larger in
winter than in summer (because of the stability of the atmospheric boundary layer).
What is the case should be in our case study?


I'm really looking forward to receiving your response as soon as possible.

Best Regards,
Ahmed Adawy
PhD student
