Federico Alzamora Previtali

Hello Pritesh, 

No inconvenience at all! The documents on the link that you shared are from Fluent 12 (2009). I see that from Fluent 18, the option was removed, but the reason is not explicitely documented in any of the release notes.

To add to this, I must say that we typically support the current release, today 23R1, and the two previous releases, today 22R2, 22R1.
