Reading .msh file issue

[hamilton-eng]

Having issues reading msh file, not sure if this is a compatibility issue? what sort of .msh files can be used by the api?

using a test .msh file from url below

https://github.com/amandaghassaei/msh-parser/blob/main/test/msh/stanford_bunny.msh

from ansys.meshing import prime
from ansys.meshing.prime import lucid

prime_client= prime.launch_prime()
model= prime_client.model


    

mesher= lucid.Mesh(model)
mesh_file_name= r"tests/stanford_bunny.msh"
mesher.read(mesh_file_name, append=False)
cdb_file_name= r"data/output/cdb_file.cdb"
mesher.write(cdb_file_name)

Traceback (most recent call last): File "c:\Users\User\tests\Ansys_geom.py", line 12, in <module> mesher.read(mesh_file_name, append=False) File "C:\Users\User\miniconda3\Lib\site-packages\ansys\meshing\prime\lucid\mesh_util.py", line 76, in read prime.FileIO(self._model).import_fluent_meshing_meshes( File "C:\Users\User\miniconda3\Lib\site-packages\ansys\meshing\prime\core\fileio.py", line 304, in import_fluent_meshing_meshes result = super().import_fluent_meshing_meshes( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\User\miniconda3\Lib\site-packages\ansys\meshing\prime\autogen\fileio.py", line 352, in import_fluent_meshing_meshes result = self._comm.serve(self._model, command_name, self._object_id, args=args) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Users\User\miniconda3\Lib\site-packages\ansys\meshing\prime\internals\error_handling.py", line 515, in wrapper_error_code raise PrimeRuntimeError( ansys.meshing.prime.internals.error_handling.PrimeRuntimeError: Reading mesh failed.

I'm also trying to import .STL

import ansys.meshing.prime as prime
from ansys.meshing.prime.graphics import Graphics

prime_client = prime.launch_prime()
model = prime_client.model
mesh_util = prime.lucid.Mesh(model=model)



input_file = r'tests/plane.stl'

file_io=prime.FileIO(model)
file_io.import_cad(
    input_file,
    params=prime.ImportCadParams(model=model, length_unit=prime.LengthUnit.MM),
)

# display the rear wing geometry without the enclosure
display = Graphics(model)
display(update=True)
part= model.get_part_by_name('plane')
part_summmary_res = part.get_summary(prime.PartSummaryParams(model=model))

Error

I'm using 0.4 documentation and have 0.4 pyprimemesh with 2023 R2 Academic

Hi @hamilton-eng,

The stanford_bunny.msh is not a Fluent .msh format. Currently we do not support non Fluent .msh formats.

Regarding the stl import can you verify if stl import is working for other files or if this is file specific?

You could try the following for example:

input_file = prime.examples.download_f1_rw_drs_stl()

I hope this helps!

[hamilton-eng]

from ansys.meshing.prime.graphics import Graphics

prime_client = prime.launch_prime()
model = prime_client.model




#input_file = r'tests/plane.stl'




input_file = prime.examples.download_f1_rw_drs_stl()
file_io=prime.FileIO(model)
file_io.import_cad(
    input_file,
    params=prime.ImportCadParams(model=model, length_unit=prime.LengthUnit.MM),
)
display = Graphics(model)
display(update=True)```

Hi @hamilton-eng ,

Please can you check that the environment variable AWP_ROOT232 is set correctly to your Ansys installation directory? The path should end like "\ANSYS Inc\v232" for example.

This should be set during installation but please confirm this is setup.

Thanks

[hamilton-eng]

Thank you, yes it appears to be in the directory

C:\Users\User>echo %AWP_ROOT232%
C:\Program Files\ANSYS Inc\ANSYS Student\v232

Hi @hamilton-eng

Please share the resulting log file from the temp folder (\AppData\Local\Temp) so that we can try and see what the issue is?

Thanks!

Hi @hamilton-eng,

Thank you for your help on this issue.
If it is possible please could I ask you to send some additional files for debugging? There should be the following two additional files:

1. ansyscl.DESKTOP-VMGC4IP.log
2. licdebugANSYS PRIME

Thanks!
