🐞 Description of the bug

Below code is running fine in windows system. However this code is not running inside Linux environment.

I want to use this geometry further in Mechanical. As Discovery or spaceclaim geometry is not supported inside Linux so I used geometry service and use .pmdb format but I cannot export .pmdb file.

📝 Steps to reproduce

Start a modeler session

modeler = launch_modeler()
print(modeler)

design_name = "ExtrudeProfile"
design = modeler.create_design(design_name)

sketch = Sketch()
sketch.circle(Point2D([10, 10], UNITS.mm), Quantity(10, UNITS.mm))
cylinder = design.extrude_sketch("SingleBody", sketch, Quantity(10, UNITS.mm))

pmdb_path = design.export_to_pmdb(location=geometry_path)
modeler.close()

error "
raise GeometryExitedError(
ansys.geometry.core.errors.GeometryExitedError: Geometry service connection terminated: The AnsysSCPlugin.PluginAddin needs to be loaded in order to export to PMDB format.

Hi @harikrushna171 -- thanks for opening this issue!

Could you elaborate a bit more on the following points?

• Which Ansys product are you connecting too? Is it The Geometry Service (based on Linux)?
• Can you confirm that the GeoemtryService is installed on your machine?`- Wherever your Ansys products are installed, there should be a folder called "GeometryService"
• What version of PyAnsys Geometry are you using? (i.e. python -c "from ansys.geometry.core import __version__;print(__version__))

[harikrushna171]

hi, @RobPasMue , thank you for connecting.

• ANSYS 25R2, Geometry Service running on Linux. Everything works well up to the Plot of cylinder command.
• Previously, it showed the error "Geometry services is not initialized," but now it runs without issues and I can view the cylinder. Please see attached image

• It is 0.11.0

@harikrushna171 thank you for the heads up!

@RyanJWard are you aware of issues with PMDB export in 25R2? I thought this was working fine

[RyanJWard]

@harikrushna171 Do you have export ANSYS_GEOMETRY_SERVICE_ROOT=/my_path/to/core_geometry_service set? Can you check for a log in v252/GeometryService/Logs

[harikrushna171]

Hello, @RyanJWard ,

Thank you for support and sorry for late reply,

• I setup "ANSYS_GEOMETRY_SERVICE_ROOT=/my_path/to/core_geometry_service" and it is working fine. As show in above image i can launch geometry service.

• However, "design.export_to_pmdb" this specific command is not working.

• "v252/GeometryService/Logs" I dont have Logs file.

• I have AnsysSCPlugin.25.2.dll installed correctly "ansys2025r2/ansys_inc/v252/GeometryService/CADIntegration/Plugin> ls
  AnsysSCPlugin.25.2.dll AnsysSCPlugin.25.2.xml"

from ansys.geometry.core import launch_modeler_with_core_service
from pint import Quantity
from ansys.geometry.core.math import UNITVECTOR3D_Z, Frame, Plane, Point2D, Point3D, UnitVector3D
from ansys.geometry.core.misc import UNITS
from ansys.geometry.core.sketch import Sketch

modeler = launch_modeler_with_core_service(version=252)
print(modeler)

design_name = "ExtrudeProfile"
design = modeler.create_design(design_name)

sketch = Sketch()
sketch.circle(Point2D([10, 10], UNITS.mm), Quantity(10, UNITS.mm))

body = design.extrude_sketch("SingleBody", sketch, Quantity(10, UNITS.mm))

body.plot()
pmdb_path = design.export_to_pmdb()
modeler.close()

@harikrushna171 Can you try replacing modeler = launch_modeler_with_core_service(version=252) with modeler = launch_modeler_with_core_service(version=252, enable_trace=True, server_log_level=0) this should generate a log

[RobPasMue]

It could be a license server assignment issue as well -- @harikrushna171 could you confirm that you are storing your license server IP/address under the environment variable LICENSE_SERVER, ANSRV_GEO_LICENSE_SERVER, or ANSYSLMD_LICENSE_FILE? (this is the precedence order BTW - from first checked to last)

[harikrushna171]

@RyanJWard,
Thank you for the update. I tried your suggestion, but it still isn't generating a log file in "/XXXX/v252/GeometryService/Logs".
However in error " The AnsysSCPlugin.PluginAddin needs to be loaded in order to export to PMDB format."

but I have this file in installation directory "GeometryService/CADIntegration/Plugin".

@RobPasMue,
I am able to launch the modeler without any errors, generate geometry, and view it in the VTK viewer (PyVista). (only design.export_to_pmdb command is giving error) So, I believe the license and installation directory are correct. I will also check with my IT person.

[RobPasMue]

@harikrushna171 -- could you do the following change to your code?

pmdb_path = design.export_to_pmdb()
# --- START ---
logfile = modeler.get_service_logs(all_logs=True, dump_to_file=True)
print("File available at:", logfile.absolute())
# --- END ---
modeler.close()

This will dump your server logs to a specific file.

[harikrushna171]

@RobPasMue

• It didn’t execute because design.export_to_pmdb() comes before the log file. (same .pmdb export error without log file path)

• When I paste it right after launching molder, it shows the following error.

• "design.export_to_disco()", When i used this command It export geometry without error. However, I cannot open this geometry as I am in Linux environment and Discovery is not supported.

[RobPasMue]

Right - good catch, of course... if the export method is failing you would never reach there. But what happens if you:

try:
    pmdb_path = design.export_to_pmdb()
except Exception:
    pass
# --- START ---
logfile = modeler.get_service_logs(all_logs=True, dump_to_file=True)
print("File available at:", logfile.absolute())
# --- END ---
modeler.close()

Does it still throw an error when you request the logs?

@RobPasMue,

FYI, I can export as .dsco, .scdocx, .xmt(bin and txt).

I want to use .pmdb export as it is support inside linux environment with name selection and other geometry feature like beam cross section etc.
