Hi All,

Whenever we try to run identifySubdomains.exe, we receive an error from Windows saying that the program has to stop working. It would be perfect if you can provide support/solution on this issue.

Hi Onur, welcome to the forum!

Could you post the complete error message?

The check at that line of code fails if multiple nodes were found in the mesh. Probably you have some duplicate nodes. Or the search-radius you specified is to large. To investigate this we would need the meshes.

Some errors can be detected with `checkMesh -v your_mesh.vtu`; would you try that as well?

Hi Dmitri,

Thanks for your quick support. The mesh file works with a unix version of identifysubdomains, however it did not work on windows. You can find the complete error message below;

Hi Onur,

looks like we have to investigate it if there is a difference between linux and windows. Would it be possible to upload the meshes here? Or drop me an email [dmitri.naumov@ufz.de](mailto:dmitri.naumov@ufz.de).

When I divide the main area into two areas with different grid sizes, an error will be reported when identifying Subdomains. However, if the grid size is set to the same parameter in GMSH, the tool will not report an error.
