@hpohekar Can I provide an absolute path within the client machine to the file_name argument of solver.file.read_case? Assume that absolute path doesn't exist within the server machine.

@hpohekar Can I provide an absolute path within the client machine to the file_name argument of solver.file.read_case?

@mkundu1 Yes, I have tested both paths. Following works fine as well.

from ansys.fluent.core import connect_to_fluent
from ansys.fluent.core.utils.file_transfer_service import RemoteFileTransferStrategy
file_service = RemoteFileTransferStrategy("10.18.44.179", 50000)
solver = connect_to_fluent(ip="10.18.44.179", port=51344, password="5scj6c8l", file_transfer_service=file_service)
solver.file.read_case(file_name="/home/hpohekar/mixing_elbow.cas.h5")
solver.file.write_case(file_name="written_remote.cas.h5")

Is changing to Fluent installation directory necessary? User may not have write permission at the installation directory.

Fluent's working directory can be anywhere. The only requirement is that the docker container should be run from Fluent's working directory.
