Seamless File Handling - Ansys Lab #2138

hpohekar · 2023-10-13T11:08:13Z

We were doing following steps to read and write a case file in the Ansys Lab

meshing.upload(file_path="read/elbow.cas.h5", remote_file_name="uploaded_elbow.cas.h5")
meshing.tui.file.read_case("uploaded_elbow.cas.h5")

meshing.tui.file.write_case("written_sample_elbow_tui.cas.h5")
meshing.download(file_name="written_sample_elbow_tui.cas.h5", local_file_path=".")

Now we are handling upload and download part internally. So, we just need to execute following steps to read and write a case file.

meshing.read_case("read/elbow.cas.h5")
meshing.write_case("write_meshing_sample_elbow.cas.h5")

upload to upload files if pypim is configured.
download to download files if pypim is configured.

@hpohekar there was a new 2024 R1 container release about 2 hours ago, that is probably why the tests are failing, going to create an issue tracker for this

@raph-luc I see. Thanks for the update. These are failing in both this and #2131 PR.

These methods will work for both local PyFluent sessions and Ansys Lab. We are handling it on basis of whether PyPIM is configured or not.

@hpohekar You are right, sorry for my confusion: I had misunderstood what _pypim_upload() does. The docstring and function name are misleading in my opinion, it only uploads using PyPIM if it is configured, if it is not then it just executes the callback defined (going to make a separate suggestion regarding this)

@raph-luc No worries at all. Your suggestion will be helpful. Thank you.

Related to my previous points: the discussion with @seanpearsonuk made me realize that this read_case() implementation won't work with local/container Fluent sessions when specifying files not in the current working dir, i.e. inside folders or when providing an absolute path, as only the basename is being passed to the actual read command

Yes, I verified and your point is correct. I just realized that after refactoring I need to update file_name passed to on_uploaded callback.
