🐞 Description of the bug

On WB, Fluent cell is connected through server info file:

server_info_file = wb.start_fluent_server(system_name= "FLU")

And Fluent is launched. using PyFluent command: fluent_session = pyfluent.connect_to_fluent(server_info_filepath= server_info_file)

However, when exit command is passed, Fluent GUI does not get closed.

Following is the test script to reproduce:

################################################## from ansys.workbench.core import launch_workbench import ansys.fluent.core as pyfluent

Please change these paths

client_dir = r'D:\users\mvani\PyWB\PyWB-examples\pyfluent_mixing_elbow\client_work_dir' server_dir = r'D:\users\mvani\PyWB\PyWB-examples\pyfluent_mixing_elbow\server_work_dir'

host = 'localhost' release = '241'

wb = launch_workbench(release=release, server_workdir=server_dir, client_workdir=client_dir)

Create Fluent system on WB

wb.run_script_string('template1 = GetTemplate(TemplateName="FLUENT")') wb.run_script_string('system1 = template1.CreateSystem()')

Launch Fluent

server_info_file = wb.start_fluent_server(system_name= "FLU") fluent_session = pyfluent.connect_to_fluent(server_info_filepath= server_info_file)

fluent_session.exit()

#################################################################

✅ Expected behavior

After exit command is passed, Fluent UI should close after appropriate WB actions are complete (like saving cas/dat files) and updating WB cell status.

📝 Steps to reproduce

1) In the test script provided under "Description of the bug", change the "client_dir" and "server_dir" paths 2) Execute the script

This script launches WB, creates Fluent system and launches Fluent.
However, at the end, Fluent GUI does not close (script has last command for exiting fluent)

@franknli Could you please look into this issue.

Hi @mkvani

PyFluent's exit command does not necessarily close the Fluent application - it probably depends on the state when the service was brought up: the behavior might be different when the PyFluent was started out of Workbench. Ultimately this is a PyFluent behavior that PyWorkbench cannot control.

However, you can always close Fluent application using existing Workbench commands, as illustrated by the Jupyter Notebook pasted below:
