Fluent loading error while opening through Pyfluent

[nakul-07]

Fluent is quitting as soon as in opens if loaded through PyAnsys, Is there a way to correct this?

Please share the versions of PyFluent and Fluent and how Fluent is launched from PyFluent.

I have tried all the versions of PyFluent from 0.16.0 to 0.17.dev2, and ansys version 22R2

following message is coming after starting a fluent session

@nakul-07 I can't reproduce that issue. Your Fluent transcript output indicates that the session is being closed, and that is probably being caused by your Python interpreter exiting.

If you are launching Fluent using PyFluent, and do not want to use PyFluent/Python itself, set cleanup_on_exit=False for your launch_fluent command

See the documentation: https://fluent.docs.pyansys.com/version/stable/api/general/launcher/index.html#ansys.fluent.core.launcher.launcher.launch_fluent
