You must define the freestream edge so that the freestream momentum thickness Reynolds number can be transported into the boundary layer.

Create a field function (Tools > Field Function).

Define the field function. The Help file of CCM+ uses this as an example:$WallDistance > 0.005?1:0
(if the wall distance is larger than 5 mm, then that is the freestream; otherwise, it's the boundary layer).


In Continua > Physics > Models > Gamma ReTheta, set the Free Stream Edge to your user-defined field function.
