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!

ERROR: child process exited abnormally

Greetings

I'm working in my simulation with the open delft 3d, and I succesfully compile the code on Windows, without any problems. I have prepare all the data for my simulation, and when i try to run the code this message appear on the Delft 3d GUI:

Part I - Initialisation Time Dep. Data module...
runid : delft_01
*** no slip defined at walls
Part II - Creating intermediate files...
ABORT: error returned by tdatmain
Flow exited abnormally

ERROR: child process exited abnormally
- Starting "d_hydro.exe" may give more information:
- Run "deltares_hydro.exe <INI-inputfile> -keepXML".
- Run "d_hydro.exe TMP_config_flow2d3d_<processId>.xml".

I looked in the forum for some help with this and i found that some people has the same problem. Qinghua Ye answer this person, but i'm still lost with this problem. I

http://oss.deltares.nl/web/opendelft3d/general/-/message_boards/view_message/163530

I also check the FAQ, and found a similar error. So I excecute the code following that instructions (On Windows, the message 'Cannot load component library "flow2d3d.dll"' appears), and the message in cmd of windows is the same that above.

I don't know what am i doing wrong, if anyone can help me i will appreciate it.

Thanks for your time and answer.

Hi Gabriel,

There are many reasons which might invoke this message.

Can you provide more information?

Hello Qinghua,

I will try to detail what i have done so far, but if you think there is something that i am missing, please let me know:

1. I compiled de code succesfully for windows.
2. I copy de w32 folder generated in the compilation, in my Delf 3d installation directory.
3. I setup my test case with all the data and configure the mdf file with the open delft GUI, and also prepare all the input files.

With all of this done, the last step is running the simulation. So when I try to do this the error this error appears:

Part I - Initialisation Time Dep. Data module...
runid : delft_01
*** no slip defined at walls
Part II - Creating intermediate files...
ABORT: error returned by tdatmain
Flow exited abnormally

ERROR: child process exited abnormally
- Starting "d_hydro.exe" may give more information:
- Run "deltares_hydro.exe <INI-inputfile> -keepXML".
- Run "d_hydro.exe TMP_config_flow2d3d_<processId>.xml".


I think that it could be a problem with the installation of the excecutable, because the model is just up to run. And if the problem is in an input file, i think that the error will mention something about that input file.

I hope this could be more specific.

Thanks a lot for your answer.

Best regards.

hi Gabriel,

Is it possible the environment variables are not correctly set?

You might use the win32 at the same folder and use the batch files to run your model locally.

Hello Qinghua,

I want to ask you if it is possible for you to give me an explanation of how to setup the environment variables? And also, what should I do after compiling the code?
I suspect that I am missing something but i don't know what is, because I don't have the steps very clear.

I really appreciate your help with this issue,

Thanks again.

dear Gabriel,

The environment variables could be set in 2 ways. By default, if the Delft3D system is installed, the variables will be set. Or you may set them by hand, even though that is not suggested.

There is another way to walk around this. Use the batch files. You could find examples in the examples folder with the open source code. In the batch file, the variables are preset.

Would you try?

Hello Qinghua,

Thank you very much for your help. I solved my problem setting up a batch file, for my test case.

My best regards.
