I did an analisys in steady state, interface between steel and air (Air Gas Ideal), a temperature range of 77 F to 770 F in the analysis.

If the analisys has a bouyancy reference density of 1.05 kg/m^3 and other analysis has a bouyancy reference density of 1.1 kg/m^3. The boundary conditions are the same in both cases, Why did I find a huge difference in the results?
