PyFluent writing animation pathline on Linux

Jessica

I am trying to save a pathline file for ANSYS Fluent using pyfluent on linux (Ubuntu 24.04) by running the command

solver_session.execute_tui(f'solve/animate/pulse/write {specific_result_filename} {frames_output_dir}')

It works on Windows, but on Linux it gives the error <solve/animate/pulse/w Error: invalid command Error Object: "pulse">

When I run the exact TUI command on the Fluent GUI in Linux, it works as well. It's only with PyFluent (import ansys.fluent.core as pyfluent).

I also tried using both commands below, which led to other errors. Is this a limitation with Linux and PyFluent?

solver_session.tui.solve.animate.pulse.write(specific_result_filename, frames_output_dir)

solver_session.settings.results.graphics.pulse.write(object_name = specific_result_filename, file_name = frames_output_dir)

Hi @Jessica that's an interesting question! I have tagged the @PyFluent-Scripting-Team in case they are able to help. It might be to do with your PyFluent versions between the systems? As I understand it there are changes ongoing to the TUI at the moment (I think?) so it might not be surprising you see different results across different versions.
