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!

Dashboard bca file assignment dimension mismatch

Hello everyone,

I am trying to setup a flow model, but I am repeatedly facing the following error when I try to generate tidal constituents from TPX 7.2 using the Delft Dashboard:

>> Reading: tpxo72.nc - h
>> Subscripted assignment dimension mismatch.

so, the .bca file is not generated!

This error occurs in both platforms Windows 7 - Matlab R2012b and Linux Gentoo - Matlab R2014.

The following .bnd file was generated automatically in the Dashboard:


South1               R A     3     1    27     1   1.0000000e+03 Uniform unnamed unnamed
South2               Z A    28     1    52     1   1.0000000e+03 unnamed unnamed
South3               Z A    53     1    77     1   1.0000000e+03 unnamed unnamed
South4               Z A    78     1   102     1   1.0000000e+03 unnamed unnamed
South5               Z A   103     1   127     1   1.0000000e+03 unnamed unnamed
South6               Z A   128     1   152     1   1.0000000e+03 unnamed unnamed
South7               Z A   153     1   166     1   1.0000000e+03 unnamed unnamed
East1                Z A   167     3   167    27   1.0000000e+03 unnamed unnamed
East2                Z A   167    28   167    52   1.0000000e+03 unnamed unnamed
East3                R A   167    53   167    70   1.0000000e+03 Uniform unnamed unnamed


I changed the .bnd file in matlab editor to try to solve the problem by giving the respective names to the beginning and end of boundaries; as the following file shows:


South1               R A     2     1    27     1   1.0000000e+03 Uniform South1A South1B
South2               Z A    28     1    52     1   1.0000000e+03 South2A South2B
South3               Z A    53     1    77     1   1.0000000e+03 South3A South3B
South4               Z A    78     1   102     1   1.0000000e+03 South4A South4B
South5               Z A   103     1   127     1   1.0000000e+03 South5A South5B
South6               Z A   128     1   152     1   1.0000000e+03 South6A South6B
South7               Z A   153     1   166     1   1.0000000e+03 South7A South7B
East1                Z A   167     2   167    27   1.0000000e+03 East1A East1B
East2                Z A   167    28   167    52   1.0000000e+03 East2A East2B
East3                R A   167    53   167    70   1.0000000e+03 Uniform East3A East2B


but the problem remains.

Someone could help me, please? - Why this is happening and how to solve?

RE: Dashboard bca file assignment dimension mismatch

Hi Mario,

I am not 100% sure what is going wrong. Did you update your Open Earth Tools (or specifically Delft Dashboard). Do be of more assistance, could you upload your model setup where Delft Dashboard could not determine the boundary condiitons?

Cheers, Kees
