Hello Guys,

Can someone explain what is the difference between Ideal gas law and Incompressible Ideal gas law in Density calculation ?

Can someone also explain how to activate the Gravity in natural convection problem?

incompressible ideal gas uses ideal gas equation to calculate the density but leaves the pressure term constant and equal to the pressure specified under operating condition.
ideal gas takes the local calculated pressure for the same calculation.
the operating condition window is where you can activate the gravity for calculations
