First off, I'm glad that the forum is back online! Thanks to anyone involved with the maintenance, and hello!! to anyone who's reading this, it's nice to connect with you again!

The issue I faced is pretty simple. I noticed something very strange in my Reynolds number output parameter, it was way off.
I tried messing around with the variables and look what happens.

If I compute this surface averaged density I get some value
If I compute this surface averaged molecular viscosity I get some other value.

But if I call them together in an expression (I went for the simple ratio) they become the same!!! Just tried with the product, I get 10^-11, this means the density switched to the density value.

I'm working on Fluent 19R3 via Workbench, is there any known issue/solution/workaround?
I already tried recreating those three variables from scratch (the viscosity, the density and the Reynolds) using a different name, just in case some funny overwriting occured, but the issue persists.

Sorry if I happened to incur in some major mistake or oversight

I've checked in 2024R1 and it looks OK,

Please update to a current build and check - R19.3 is from about 2018 and there have been one or two enhancements since then.
