Hi,

I am doing simulations on aerofoil and would like to study forced transition. On hand I have predicted transition locations and would like to separate out the laminar and turbulent at the specific transition location. I have define two zone namely Laminar and Turbulent in gambit. In Fluent, there is an option to select "Laminar Zone" for a particular fluid zone where it switches off the turbulent viscosity and production terms.

I am wondering how would I go about doing this in CFX. I have tried to create two domains (laminar and turbulent) but it does not allow me to specify turbulence models "None" for the laminar domain and "SST" for the turbulent domain. I have also tried creating a subdomain for the laminar zone but no luck so far. Could anyone shed some light?
