Hi, i have an analisys in steady state, interaction between steel and air (Air Gas Ideal), a temperature range of 77 F to 770 F.

The question is: I did an analisys with a bouyancy reference density of 1.1 kg/m^3 and other with a bouyancy reference density of 1.2 kg/m^3. The boundary conditions are the same in both cases, Why did I find a big difference in the results?

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?
