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!

Output for Specific Locations

I am trying to output a table file for three locations and I get this error in the print file:
TABLE 'Observat' HEAD 'Observations\31.locn1t001 .tab' XP YP DEP HS DIR RTP T
** Error : Illegal keyword: T

DSPR UBOT WIND VEL
** Error : Illegal keyword: DSPR
** Error : Illegal keyword: UBOT
** Severe error : Read error with variable VEL
-> VEL item=
** Severe error : No value for variable DIR
-> DIR item=

$

$

TEST ITEST= 0 ITRACE= 0

COMPUTE STAT 20080924.000000
** No start of computation because of error level: 3
** To ignore this error, change [maxerr] with the SET command

STOP

Any help would be appreciated

Hi Kristine,

The line "TABLE ... HEAD ... ", written by Delft3D-WAVE, has a maximum length of 79 characters. Using the file name 'Observations\31.locn1t001 .tab' does not fit and the line is truncated. The easiest solution is using a shorter file name. When the line(s) are correctly written, it should read:
TABLE 'Observat' HEAD 'locn1t001 .tab' XP YP DEP HS DIR RTP TM01 _
                                       DSPR UBOT WIND VEL


Regards,

Adri
