Default Natural convection

Hi to all. I am using Ansys 10 to simulate natural convection in a annulus but I want to use the Boussinesq aproximation for the temperature dependence of density. How can I use this aproximation in Ansys?

Thank you

I suppose the question about CFX? Boussinesq approximation is used by default I suppose - you just need to set BC and laminar flow as well as the define density dependence of temperature as expression, for example.
