Hi Everyone,

 

I need some advice on how to calculate downforce on a sports car.

 

My objective is to simulate a car without spoiler/rear wing vs a car with spoiler/rear wing.

 

I want to calculate downforce at the front wheels vs rear wheels. I made a slight cut at the bottom of wheels to simulate road contact.

 

Q1. Is it proper to put surface goals at those areas? (Surface goal component force Y)

 

Q2. Any other ideas to measure downforce more efficently?

 

Q3. External flow, or internal flow (design a tunnel and place the car model in it). Which is better?

 

Appreciate if help/advise can be contributed coz I need these answers ASAP
