Boussinesq and Natural Convection

I am trying to model natural convection in a closed model, and I want to use Boussinesq approximation, my Ra number is 10e10, my question is, where to specify the thermal expansion coefficient, because the manual says specify it in the material panel after you specify the density, but I was not able to find it or find any place to add it. my second question is do you have any recommendations how to attack this problem with this high Ra number, which is going to be turbulent, can you please provide some details for the solution procedure. Thanks
