Questions regarding setting up a Jet flow for low Reynolds number.

Dear @sbryngelson and @wilfonba,
I am a new user of MFC trying to get the hang of it. I want to simulate a jet flow for low reynolds number eg: Re=3000 using MFC code. I take the case.py file shared by @wilfonba for 7 Jets injecting air at Mach 1.5 into stagnant air. I am using MFC v4.9.2.
In the end of the file it is given that "fluid_pp()%Re()": 1.81e5 . My understanding is that this fluid property is the Real Shear viscosity of fluid (air). This should be 1.81e-5 Pa.s Maybe i understood it wrongly. Could you please clarify what this Re quantity means?

The Re quantity you put there is equivalent to 1/\mu (where \mu is the Newtonian shear viscosity) if all of your other units are consistent with one another. Hope this helps!

Okay. Thanks for the clarification.
