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!

[error tdatmain] Terminate called after throwing an instance of 'char const

Hi everybody,

I'm trying to run an instance under Ubuntu. I've prepared my *.mdf file with the GUI under Windows, before running in Ubuntu console with:
./run_flow2d3d.sh myfile.mdf

I've also prepared the config_d_hydro.xml file, calling myfile.mdf and myfile.url in the code.

After this process, I've obtained the following error after running ./run_flow2d3d.sh myfile.mdf:

I really appreciate your help.
Thanks for your time.

Hi everbody,

I have solved part of my problem by using answers of this post http://oss.deltares.nl/web/delft3d/general/-/message_boards/view_message/55318
However, now I have new errors:

Part I - Initialisation Time Dep. Data module...
runid : MDFvillarrica01
Part II - Creating intermediate files...
Part III - Initialisation of the Execution module...
Part IV - Reading complete MD-file...
Flow exited abnormally
Check diagnosis file
terminate called after throwing an instance of 'char const*'
Aborted (core dumped)

At tri-diag file, I found this messages:

*** MESSAGE Using UNESCO density formulation by default
*** WARNING Using default momentum solver "Multi Directional Upwind Explicit"
cyclic can not be used as momentum solver in z-model
*** MESSAGE DRYFLP and DPSOPT both specified in MD-file. Using DPSOPT: MIN
*** WARNING Using default transport solver "Van Leer-2 (explicit)"
cyclic-method can not be used as transport solver in z-model

So now I am searching where to change momentum solver and transport solver under Linux/Ubuntu.

Any advice will be very helpful to me.
