car downforce

I am playing around with the flow simulation for a car to see how best to create down force. I keep having a few issues pop up and wanted to see if any body here could help me out.


1) When I look at the the force normal to y (as in the attached pic) I am seeing that when "better" aero is applied, this number goes from negative to positive. Is that correct? Does a positive number indicate more down force?


2) For some reason when i do a cut plot towards the center of the vehicle, it doesn't show, move a bit outside the center and it does. What could be causing this?


3) Not matter how i change the parameters, all the selected surfaces show one color when looking at pressure on the surface plot. I dont know why
