🐞 Description of the bug

I am using PyFluent 0.20 with Fluent 24R1 and launching my code in Linux environment and facing an extreme slow down. apparently Fluent is not taking the resources I am sending to the launcher. My job is not taking external resources and is not traceable.

📝 Steps to reproduce

activate your virtual environment, then launch the Fluent through Pylauncher using slurm:

import ansys.fluent.core as pyfluent
import os
import math as math
import pprint
def launcher(ss, ver, prec, core1, mode1, gui, clean1):
      

      a1="-pib -cfluesh"
      slurm=pyfluent.launch_fluent(scheduler_options={"scheduler":"slurm", "scheduler_headnode":"cdc01dcv01",
      "scheduler_queue":"cdc03gen","scheduler_account": "ace"} , additional_arguments=a1, product_version=ver,precision=prec,processor_count=core1,mode=mode1,show_gui=gui,cleanup_on_exit=clean1)
           
      ss=slurm.result()
      
      return ss

# loading Fluent
# this section checks for server file existance. 
# if server file exists, the session will connect to 
# an existing Fluent session. otherwise, it will launch a new session.
# when you exit Fluent, make sure you erase the server file for future connection.

from launcher import *
server_file='server.txt'
server_file_check=os.path.isfile(server_file)

if not server_file_check:
    s1=pyfluent.launch_fluent(product_version=ver, precision=prec, processor_count=core1, 
                              mode=mode1,show_gui=gui,cleanup_on_exit=False,py=False)
    s1.tui.server.write_or_reset_server_info('server.txt','no')
else:
    s1=pyfluent.connect_to_fluent(server_info_file_name=server_file)
