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!

dear delft3d master user..

Is there a way to input wave data (e.g. radiation stresses) that
have already been calculated by a wave model other than
SWAN into the Delft3D hydrodynamic model?
We have an existing wave model for an area and we want to couple it to a hydrodynamic/sediment transport model.

forum user said,
first.
make communication file(com-*.dat) yourself.
But, it was used for delft3d openearth tool.
Then, what is the convert file in openearth tool?

In definite example..
we have 1 month swan result.
we want to convert this data to delft3d input file for calcuate sediment modelling.

this data follow:

For general user, how to convert delft3d com-*.dat for this file?



second.
If i made com-swan.dat, forum master?(concerned person) said that user used this script for delft3d wave-currnet interaction.

\openearthtools\trunk\matlab\applications\delft3d\delft3d_createTrim.m


I try to download this adress, and findout this script. But, i don`t know how to use this program.

Have you process or example for user??



openearthtool package download ok.

In detail, program run and make input example are not suggest openearthtool..

please answer me.
