Hello ..In Define -->materials ..properties can be either defined constant or as a function of temperature (polynomial etc). For other properties its fine but for density I want to use both boussinesq and polynomial.

Can anyone help...how to do that?

hi meenu,

I think....we cant use two density formulations at a time...

boussinesq is apt only for lesser temp difference problems..

if it is natural convection problem..you can go for incompressible ideal gas.
