Error with scheme eval

[francisco-jimmy]

Hello,

I have randomly encoutered the following error when using scheme_eval. I cannot reproduce it consistently. Launching the same pyfluent script sometimes gives the error, sometimes doesn't (in the same system, with the same files).

Pseudocode that leads to the error:

solver = pyfluent.launch_fluent(
precision="double",
processor_count=processor_count,
mode="solver",
show_gui=show_gui,
)
solver.scheme_eval.scheme_eval(
f"(rpsetvar 'operating-pressure {operating_pressure})"

Error message:

Does someone know where this error comes from and how can I fix it?

Thanks in advance.

Why are you trying to use a hidden and undocumented rpvar call for that? The tui supports it with tui.setup.operating_conditions.operating_pressure

I don't see this in the settings API yet, I'll check on that.
