### 🐞 Description of the bug
I am used to launching Fluent GUI from a Windows machine connected to a Linux HPC. I am trying to adapt this workflow to PyFluent. I am struggling to launch to the HPC in my code, and haven't found good documentation on launching using PBSPro job scheduler.
This is the existing code that is not working:
solver = pyfluent.launch_fluent(
precision=pyfluent.Precision.DOUBLE,
processor_count=264,
show_gui=True,
additional_arguments='-rsh="plink -batch -i C:\Temp\ssh-priv.ppk -l bv169" '
'-nodepath=/opt/ohpc/pub/apps/ansys_inc/v241/fluent ' '-node0=XX.XXX.XXX.XX ' #cluster IP
'-setenv="FLUENT_REMOTE_SSH=1" '
'-pbs '
'-pbssubmissionhost=XX.XXX.XXX.XX' #cluster IP
)
### 📝 Steps to reproduce
Launching from the command prompt on Windows machine logged into Python environment with PyFluent installed. Previous lines of code:
import os
import pandas as pd
from ansys.fluent.core import launch_fluent
import ansys.fluent.core as pyfluent

Contributor guide
Research direction
Start with the reported ansys.fluent.core.launch_fluent call and its PBS Pro additional_arguments from a Windows command prompt using the stated Python environment. Reproduce the failed Windows-to-Linux HPC launch and determine the documented invocation needed for PBS Pro; done means the workflow launches Fluent successfully or the required limitation is clearly documented.
