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!

"Edit Depth" does not Work for Spherical Coordinates

"Edit Depth" does not Work for Spherical Coordinates

Hi all,

I am trying to edit the depth values on grids with Spherical Coordinates in QUICKIN. However, by clicking on a grid point, no window opens for further changes. The View --> Depth is selected as Coloured Dots. It seems that everything works pretty well on Cartesian Coordinates though. Any suggestions on what might be wrong here? Is it possible to still edit depth values within Spherical Coordinates?

Any comments welcome!

Best regards,
Angang

Angang,

I'm having the same issue. I was told to try restarting the program, but that does not fix the problem. Did you ever get any resolution?

Thanks.

Hi, Andy

To edit depth values on a grid with spherical coordinates try the following combination:

Select "Edit Depth". Than press the Tab key while the cursor is on a grid point. By pressing the + - keyboard keys change the chosen depth value. You can also delete a depth point pressing D (it would have the -999 value).

Cheers

It works! Not as accurate as direct input, but gets me on the right path. Thank you!

Hello all,

I have had this problem in the past.
In my version of QUICKIN, I have an option to get around this by going to, View --> Spherical Co-ordinates , and selecting the option 'Plane Co-ordinates'.
This allows you to edit depths in the usual way, and can be toggled back once you are finished.

I hope that works,

Cheers,

Jack
