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 generating batch file

Hello all,

I'm brand new to using Delft Dashboard, so bear with me. I'm trying to set up a Delft 3D flow model, but for some reason, a batch file is not being generated. These are the errors I'm getting:

??? SWITCH expression must be a scalar or string constant.

Error in ==> ddb_writeBatchFile at 80
switch handles.Model(md).version

Error in ==> ddb_saveMDF at 613
ddb_writeBatchFile(runid);

Error in ==> ddb_saveDelft3DFLOW at 83
handles=ddb_saveMDF(handles,i);

Error in ==> ddb_menuSelect at 83
feval(cb,opt);

??? Error while evaluating uimenu Callback

All the other files have been generated. Could this be a problem with my version of matlab (v. 7.5.0, R2007b)?

Thanks!

Hi Sarah,
Do you have Delft3D installed? If not, Delft Dashboard gets confused about how to write the batch files for running the mode. I'm currently trying to fix this bug.
Cheers,
Maarten van Ormondt
