Hello everyone, I'm doing a basic simulation of airflow over a passenger car in Ansys.

I'm trying to create some sort of visualization to show how airflow is affected by adding a rear roof wing of a car traveling 60 mph (roughly 27m/s)

My theory is that it will slightly help to reduce drag at the cost of downforce.


/insert thats not how this works meme

/insert I have no idea what I'm doing meme


I'm going to include my workbench files

Does anyone have any tips for modeling this better?
-Should I draw the entire car?
-Should I run multiple tests at different speeds?

Hello ApuME,

Since you want to simulate a passengar car, I would suggest checking out Ahmad body first. However, I think that added wing will increase drag in 3D even if does not increase in 2D. This is due to vortices generated at the wingtips and (negligibly) increased surface area.
