It seems we're deleting the local copy and returning it ?? in launcher pyworkbench/src/ansys/workbench/core /workbench_client.py def start_fluent_server(self, system_name): """Start the PyFluent server for the given system in the Workbench project. ...

📝 Steps to reproduce

basic code

import ansys.fluent.core as pyfluent from pathlib import Path from ansys.workbench.core import launch_workbench

wb_script_file = Path("./modules/wbScript.txt") # system with fluent setup wb = launch_workbench(release="241") wb.run_script_file(wb_script_file.absolute())

fluent_file_info = wb.start_fluent_server("FFF") print(fluent_file_info) fluent = pyfluent.connect_to_fluent(server_info_file_name=fluent_file_info)
