Has anyone faced this error in meshing before? Occured at share topology step.

I do not have an object, surface or a named selection named as "platform" in my domain. At this point, I am not sure if its a bug but I can't resolve the issue.

Thanks in advance

Are you using Fluent meshing for meshing?

Yes, I am using the stand alone Fluent Meshing

Hello Mit,

What application are you using? Share topology is not done as part of the mesher. This is done inside SpaceClaim or DesignModeler. SpaceClaim has a built-in mesher which is a more advance multizone, but otherwise the geometry is usually transferred to the Meshing Application or Mechanical inside workbench for meshing (there are a few other choices on where to mesh and transfer from there).

I am not familiar to this error, but the term "platform" refers to the operating system, such as Windows 10, 11, Linux Red Hat Enterprise 7, 8 , etc... The following page shows supported operating systems per application for Ansys 2023 R1 products:

I see a mention of the unbound variable error in Fluent knowledgebase solution 2041270:

Check to see if you have the below variable defined. If not, please define it.

LANG = en_US

or

LANG = C

This issue has been seen with :
RHEL 6.7 machine
German language

Hi Mj,

Fluent Meshing allows us to apply share topology as a part of its Watetight geometry workflow. I doubt the term here refers to the OS because I have always worked in the same OS system and haven't encountered such a problem.

I work with Mechanical products, so sorry that I was not familar with the Fluent error. The knowledgebase solution applies to Fluent, however. Did setting the LANG help?
