Seek command that returns zone names

[RandSim]

Hi,
I have been trying to construct a 'smart' meshing process which would query label/zone names and issue surface refinement depending on said names. Is there a command whose output would be all the zone names in a table or something?
Same question at but for the solver instead of the mesher.
Thanks you for your time!
Alex,

Skeleton code to help with understanding:
For name in zone_table:
if name contains "_ref03":
"meshing.workflow.TaskObject['Add Local Sizing'].Arguments.set_state({r'AddChild': r'yes',r'BOIFaceLabelList': [name],r'BOISize': ,})"

Upping this message so that it doesn't fall through the cracks.

@RandSim This is ongoing work - please see #1492. We'll add more queries to that PR.

[mkundu1]

The feature won't be fully available in 2023R2. Meanwhile, we can execute the Fluent meshing queries from PyFluent to get the same info:

>>> meshing.scheme_eval.scheme_eval('(tgapi-util-convert-zone-ids-to-name-strings (get-face-zones-of-filter "*let*"))') 
['inlet1', 'inlet2', 'outlet']

[RandSim]

This isn't working for me, see console below. I directly typed the command provided as is right after loading the CAD in the meshing in Watertight Workflow. The CAD contains labels 'inlet' and 'outlet'. Could you provide more instruction on how to make it work?
Thanks!

"

If meshing is your session object returned by launch_fluent it should work. Please check what is None.

[RandSim]

Thanks for all the help!
Here is the output from the fluent meshing console. As far as I can tell, meshing.scheme_eva exists. meshing.scheme_eval.scheme_eval doesn't.
It would help me a lot if we had an auto complete command feature. Is there such a thing? Tab doesn't autocomplete for me.

As pointed out in my previous reply meshing here has to be the object returned by launch_fluent. The same instructions do not work otherwise.

[RandSim]

Sean,
Thanks for your assistance thus far. Unfortunately, I still have the same behavior as before when I launch the code below with the command launch_fluent as you requested. Any help on this matter would be much appreciated. Perhaps I am missing an import? Perhaps something else?
Please note that I updated the latest core module for pyFluent with "pip install ansys-fluent-core" and rebooted my computer just to make sure.
Thanks again,
Alex,

The code that I ran is:
"import ansys.fluent.core as pyfluent
meshing = pyfluent.launch_fluent(precision="double", processor_count=8, mode="meshing", show_gui=False)
meshing.workflow.InitializeWorkflow(WorkflowType=r'Watertight Geometry')
meshing.workflow.TaskObject['Import Geometry'].Arguments.set_state({r'FileName': r'C:/Users/alefebvre/Desktop/ClientName/code1/oml157-marketing-Rand.scdoc',"LengthUnit": "mm",})
meshing.workflow.TaskObject['Import Geometry'].Execute()
meshing.scheme_eval.scheme_eval('(tgapi-util-convert-zone-ids-to-name-strings (get-face-zones-of-filter "let"))')"

The output from the code is:
"Traceback (most recent call last):

Looks like you are finding the right scheme_eval call but what you are passing it does not look correct compared to what was suggested by mkundu1 earlier:

>>> meshing.scheme_eval.scheme_eval('(tgapi-util-convert-zone-ids-to-name-strings (get-face-zones-of-filter "*let*"))') 
['inlet1', 'inlet2', 'outlet']

Regarding intellisense, I think at some point this did get broken in VS Code. What IDE are you using and what version of the library are you using?

[RandSim]

Dan, Sean,
Not sure what changed today, but the command below is working fine. Make sure to use the command from a python file (see code below). Do not use it from Fluent command line as it seems that the object "meshing" would be a bit different then.
Hope this helps & thanks everyone for your help,
Alex,

SOLUTION
meshing.scheme_eval.scheme_eval('(tgapi-util-convert-zone-ids-to-name-strings (get-face-zones-of-filter "*let*"))')

Code that successfully tested the command
import ansys.fluent.core as pyfluent
meshing = pyfluent.launch_fluent(precision="double", processor_count=8, mode="meshing", show_gui=False)
meshing.workflow.InitializeWorkflow(WorkflowType=r'Watertight Geometry')
meshing.workflow.TaskObject['Import Geometry'].Arguments.set_state({r'FileName': r'C:/yourPath/yourFile.scdoc',"LengthUnit": "mm",})
meshing.workflow.TaskObject['Import Geometry'].Execute()
test = meshing.scheme_eval.scheme_eval('(tgapi-util-convert-zone-ids-to-name-strings (get-face-zones-of-filter "*let*"))')
print(test)
['origin-inlet-nozzle', 'origin-outlet-duct', 'origin-wall-inlet-duct']
