Re: reynold number on inlet
You can define the turbulence intensity at the inlet which can be calculated from the Reynolds number. Look up boundary conditions/inlets in the user guide to get the equation for this and the hydraulic diameter which you will also input. This is just the diameter of the inlet.
You should select turbulence specification method as 'intensity and hydraulic diameter' at the velocity inlet window, then input your calculated numbers.
As far as I know this is the only way to do it but you could write a UDF to allow you to use any variable. The UDF would be written to use an equation to convert any value to the required format.
