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!

Hello,

My name is Joao and I am a student at Griffith University, Australia. I am using Delft3D Wave to run my simulations, however, I have been facing some problems!

Basically, my domain has four boundaries, however, just three of them are open (west, north and south). Since I am trying to run my program in Non-Stationary Mode with space-varying wave conditions, I have created my TPAR files through a matlab code in order to get the exactly same configuration as explained on the Delft3D manual! I sat on the time frame menu (inside Delft3D-Wave) a time point for Wave computation of 01 12 2012 00 00 00, which matches the first line of my TPAR file representing the starting moment!

Example: 155.0003.bnd

20121203.0300 1.690 9.709 166.00 4.0
...

However, when I plot with quickplot the results the only available time is 01/12/2012 - 00:00:00, which means that it just computed that specific time, and I cant check any more time since the bar for watching several times is blocked! Additionally, despite Delft3d does not give me any errors or warnings, at the end of my command run appear this which does not seems correct!

>>...End of SWAN run

Write Wave map file, nest 1 time *************

Delft3D-WAVE finished normally

I would appreciate if someone could help me with this! Thank you very much!
