How to simulate the effect of altitude on quad lift?

Hello, I am trying to estimate the effects of reduced air density at high altitudes on the payload and attitude of a quad using a simulator. However, I found that neither Gazebo nor jmavsim seems to have these capabilities. Gazebo seems to support aerodynamics simulations only for fixed-wing aircraft. So, which tool should I use for this? Do JSBsim or Airsim support such simulations? Or should I learn the relevant concepts myself and use Simulink?
Thanks.
