Hi, I'm writing a paper and using gazebo 7 to simulate a quadrotor. One of the reviewers asked for clarification on how the wind simulation happens. Does it simply add a number (proportional to the wind velocity) to the robot's current velocity value? does it use force?

Maybe this question regards the inner workings of the physics engine and I should ask it somewhere else. I don't know.

Anyway, thank you very much!
