🐞 Description of the bug

I can use the code below to start fluent in batch mode. Using pyfluent to start then I cant pass '-rsh="plink -batch -l aaaaa"' It interpretate it as separate commands. Have tried several methods but all

run([r"C:/Program Files/ANSYS Inc/v232/fluent/ntbin/win64/fluent.exe", '3ddp', 
             '-t{}'.format(cores), '-nodepath=/mapr/danfoss4.com/apps/Ansys/v232/v232/fluent', '-node0=dkrdc01-loginnodevm',
             '-rsh="plink -batch -l aaaaa"', '-scheduler=slurm', '-scheduler_account=aaaaa',
             '-scheduler_queue={}'.format(scheduler), '-scheduler_headnode=dkrdc01-headnodevm', '-setenv="FLUENT_REMOTE_SSH=1"',
             '-sifile="C:\Temp\server.txt"'])

fluent launch string like this works: fluent.exe 3ddp -t4 -rsh="plink -batch -l aaaaa" -sifile=s1.txt

From pyfluent end the parsing code seems to be working correctly:

session = pyfluent.launch_fluent( version="3d", precision="double", mode="solver", processor_count=4, show_gui=True, start_transcript=False, additional_arguments=r'-rsh="plink -batch -l aaaaa"')

Corresponds to a fluent launch string of :

".....\fluent.exe" 3ddp -t4 -rsh="plink -batch -l aaaaa" -sifile=.....\serverinfo-0gx4tr4g.txt -nm

which launches the fluent session as expected without any issues. @jharming, could you please try out your option 2 and confirm the issue again. Thank you.

@jharming, is this bug still relevant?
