Deprecated solver.scheme_eval.exec - how to use the session.scheme command

[david-f-fletcher]

I am trying to replace the deprecated solver.scheme_eval.exec () with a session.scheme.exec(() command but when I try to run the pyFluent code with the session command i get the error NameError: name 'session' is not defined. The manual gives no information on what to do. Can you advise please and also update the documentation?

This is the updated docs.

Hi Thanks for this. I am confused as to why the 3 and 4th commands give different outputs when they are identical. What am I missing? Thanks David [cid:abe7d80e-4279-4313-8037-1cfd3a0beb08]

@david-f-fletcher, could you please provide a snippet of your findings and explain once. Thank you.

My question is very simple. In the code in the manual, it shows that session.scheme.eval("(rpgetvar 'mom/relax)") in one case returns 0.7 and the other '0.7'. My question is how can this be correct, that the same code gives two different answers?

Thanks, David

Thank you @david-f-fletcher for pointing that out. We have updated the docs with the correct syntax: #4362.

Thank you so much for helping us improve our docs.
