First of all, Fluent is a dimensional solver so you need to change the velocity, size or fluid properties to give the Reynolds number you want. Secondly, this is the CFX forum. For questions on...

The reported Re is not used for anything in the calculation and is just used to generate a warning message about turbulence if a laminar flow is modelled. And it is just a...

The purpose of the Re number reported is just a general guide for the flow, in particular to have a guess as to whether a turbulence model should be used. If it says the Re is high and a laminar flow...

I have no idae what you representative length scale is, but assuming it is the cube root of the volume of your domain I get Re=1e-5 or so. This is a tiny Re number and there will definitely be no...
