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!

URGENT: Compilation error on Windows 10 - VS15 community + IFORT18

When building the delft3d_open.sln it comes up with an error saying:

 

"flex.exe - Application error

This application was unable to start correctly (0xc000012d).

Click OK to close the application."

 

The same happens for 'byacc.exe' and everything freezes. Please advise!

 

Also, having just retried compiling, new errors came up:

"FATAL error LNK1181: cannot open input file '..\kernel\lib\x64\release\kernel.lib' "

and followed by

"vctip.exe A new guard page for the stack cannot be created"

 

I have seen some other questions in the forum with SIMILAR problems with byacc.exe and flex.exe, but their compilations still finished and they were able to see the build log. Because mine freezes (and screen blacks out) before finishing compiling, I cannot retrieve a build log either. I am new to using all of these software, and any help would be much appreciated!! Thank you.

Me too. It gives me flex.exe error (0xc0000142) and the compilation stops.

Hi All,

 

I am getting a similar 'flex.exe unable to start' error and the model does not finish compiling, but freezes. Did anybody find a solution?

VS: 2015

Fortran Compiler 16

Tag 7545

 

Thanks,

Chloe

I appreciate you probably found a solution by now, but for people who may have similar problems in the future, I found a solution that worked for me (on two different PCs).

Instead of checking out the latest tag from the svn, I checked out the trunk version of the source code.
I.e. I checked out https://svn.oss.deltares.nl/repos/delft3d/trunk/ into a new empty folder. This got rid of all errors for me. Hope this helps!

Best wishes,

Gabriel
