How to export a mesh file as STL in ansys fluent?

CoolHarrison

This is the main section of code where I try to export a mesh file:

generate_volume_mesh = workflow.TaskObject["Generate the Volume Mesh"]
generate_volume_mesh.Arguments.update_dict({"VolumeFill": "poly-hexcore"})
generate_volume_mesh.Execute()

mesh_file = r"C:\Users\forha\OneDrive\Documents\GitHub\F1car-wAI\my_mesh.stl"
session.tui.file.export.stl("ANSYS Fluent", "2024R1", "meshing", mesh_file)

The error happens at the last line of code. When that code is ran, it tells me this:

Exception has occurred: RuntimeError
menu not found
grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:
    status = StatusCode.UNKNOWN
    details = "menu not found"
    debug_error_string = "UNKNOWN:Error received from peer  {created_time:"2024-10-20T20:51:02.9016385+00:00", grpc_status:2, grpc_message:"menu not found"}"
>

During handling of the above exception, another exception occurred:

  File "C:\Users\forha\OneDrive\Documents\GitHub\F1car-wAI\fluentTest2.py", line 109, in <module>
    session.tui.file.export.stl("ANSYS Fluent", "2024R1", "meshing", mesh_file)
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^
RuntimeError: menu not found

In the Pyfluent documentation, it says that the stl class has 4 inputs; service, version, mode and path. It's possible that these inputs are wrong, but I'm not really sure what they should be changed to. It's also possible that the function is wrong, but again i'm not sure.

Hi

I have not used pyfluent, but try just adding like here (
https://github.com/ansys/pyfluent/issues/2188 ):

...tui.file.export.stl(file_name = r"C:\Users\forha\OneDrive\Documents\GitHub\F1car-wAI\my_mesh.stl")

If this does not help then post here for more help:

@CoolHarrison

Can you try not saving on Onedrive - just save on C or D somewhere.

All the best

Erik

PS: use this way:

.tui.file.export.stl(file_name = r"C:\Users....\Documents\GitHub\F1car-wAI\my_mesh.stl")

Hello Erik,

I was the one who posted that question as you advised me to do. However, this code:
session.tui.file.export.stl(file_name=r"C:\Users\forha\OneDrive\Documents\GitHub\F1car-wAI\my_mesh.msh.h5")
or this code:
session.tui.file.export.stl("D:\Pyfluent\my_mesh.msh.h5")
has ended in failure. Every single variation I'e tried with and without file_name= has always given me this error:

Exception has occurred: RuntimeError
menu not found
grpc._channel._InactiveRpcError: <_InactiveRpcError of RPC that terminated with:
    status = StatusCode.UNKNOWN
    details = "menu not found"
    debug_error_string = "UNKNOWN:Error received from peer  {created_time:"2024-10-28T18:33:43.2009622+00:00", grpc_status:2, grpc_message:"menu not found"}"

During handling of the above exception, another exception occurred:

  File "C:\Users\forha\OneDrive\Documents\GitHub\F1car-wAI\fluentTest2.py", line 215, in <module>
    session.tui.file.export.stl("D:\Pyfluent\my_mesh.msh.h5")
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^
RuntimeError: menu not found

The code from the github said that this works:
meshing.tui.file.export.stl("D:\pyfluent\FM_AAPQ13pUvWxQtxN_86052\TaskObject23.msh.h5")
But since my computer doesn't have this exact file location, I haven't been able to replicate it accurately. Instead of D\Pyfluent, my files generate in C:\Users\forha\OneDrive\Documents\GitHub\F1car-wAI. I tried making it generate in C:\Users\forha\OneDrive\Documents\GitHub\F1car-wAI\FM_LAPTOP-U99GAPOP_1260. but nothing.

In truth, I really think it would help me if I understood why the problem is happening. I'm just not sure why the file location should have any effect on the effectiveness of the code. Maybe it's a version issue or a function issue, but I can't seem to make it work. Would you like my entire code more some incite into it? Maybe something else is having an effect.
