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!

Ocean heat model input. Cloudiness.

Hello.

Data input for the Ocean heat model includes both constant "Cloudiness" and time dependent "Fraction cloud coverage". Is it the same parameter? What for the constant cloudiness is needed if the time dependent one is specified? Will be the constant one taken into account? Will be "Water surface area" parameter taken into account for the Ocean model?

Thanks.

Hi Aleksandr,

In a newer GUI (4.02.02), if "Ocean" heat flux model is chosen, then water surface area and sky cloudiness parameters are automatically grayed out. So I expect the're not taken into account during calculation.

Regards,

Dmitry
