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! 


We have launched a new website (still under construction so expect continuous improvements) and a new forum dedicated to Delft3D Flexible Mesh.

Error message relate to vs library in tools_glp

Last weekend, I downloaded the newer version of Delft3d that we can find on the trunk folder of Deltares repository. I compiled Delft3d ver. 3688 using Visual Studio 2008, Intel Fortran 11.0.61 in Windows XP. During the compilation, I got warning messages and I had only one error message, which said:
Error PRJ0019: A tool returned an error code from “Performing Pre-Build Event…”
File: vs
Project: vs(tools_gpl\vs\vs)

(I’m attaching the print screen of VS2008 that I got when the compilation process has finished).

I believed that maybe, this error could be a critical error. But I got the binaries files that we need to run Delft3d. I ran some test cases in order to know if the FLOW, WAVE and MOR modules had any problem and, I could run these cases without any problem.

It is only curiosity… does anyone know, how to fix this error?
How would this error affect my numerical simulations?

Thanks and regards.

Hi Gabriel,

Before compiling a module, a script is executed to obtain the SVN revision number and put it in a nice string together with the version number and the current date/time. Your error message says that this pre-built script execution went wrong. But only for one of the projects, namely the building of the tool vs (a stand-alone tool to extract data from nefis files). So, the full compilation succeeded, you even have a working vs.exe. The only thing that might be wrong is the version number of the vs tool. That will not influence your results.

I don't know why the error occurs on your system. A comparable script is used for all modules and they all finish without an error message except this one.

Hi Adri,

I got it!
It is good to know this error does not influence in my numerical simulations.
Thank you!

Kind Regards.
