Cannot launch fluent with working journal

[robcodesnew]

Hi all,
I have been trying to launch fluent using a solve journal I have generated. My command to do so is the following:
journal_path= "Z:/..../tmp/naca0015_aoa_0_journal_solve.jou"
cwd = "Z:/..../tmp/"
solver=pyfluent.launch_fluent(product_version = "22.2.0", version = "3d", processor_count = 12, show_gui = True, journal_filepaths= journal_path, cwd=cwd)

However this command gives me the following error:
pyfluent.launcher ERROR: Exception caught - RuntimeError
LaunchFluentError:
Fluent Launch string: start "" "C:\Program Files\ANSYS Inc\v221\fluent\ntbin\win64\fluent.exe" 3ddp -t12 -sifile="C:\Users...\AppData\Local\Temp\serverinfo-y641hgp0.txt" -nm -hidden

The command does open the GUI and identify the processors to be used, so I suspect the issue is with the journal filepath parameter.
The journal itself is correct because the exact value of journal_path pasted into the GUI's "read journal" option runs the simulation perfectly. Could anyone help me identify my mistake here?

This is a bug with Fluent 22.2, we'll look into fixing it. As a workaround, pass the journal file as an additional argument with Fluent 22.2:

solver = pyfluent.launch_fluent(product_version="22.2.0", additional_arguments="-i a.jou")

Thanks for the reply. I have another slight issue. When I run the code with product version = "22.2.0" it seems to launch Fluent 22R1. I have fluent 22R2 installed on my machine. Is there an explanation for that?

@robcodesnew try checking the value of your AWP_ROOT222 environment variable, see if it is pointing to the correct Ansys install. It should be set to something like C:\Program Files\ANSYS Inc\v222 (depending on where your Ansys 2022 R2 is installed).

Ok great! Thanks, that worked. One last question: what procedure would you recommend to launch a whole list of journals? Running the launch_fluent() multiple times? I was planning on using the journal_filepaths parameter but it seems I cannot input a list like that that with additional_arguments

To read multiple journals using additional_arguments:

solver = pyfluent.launch_fluent(product_version="22.2.0", additional_arguments="-i a.jou -i b.jou")
