drag and lift analysis of car model

Hi Guys,

I am currently trying to use cosmosflow to do some aerodynamicsimulations of flow around a car model. I have been having someproblems though and i wish i could get some help.

1) Having stated my fluid velocity, how do i develop a moving roadbeneath the car to immitate a moving boundary.

2) How do i make the wheels of the car rotate while running thesimulations as it is important for me to study flow around thewheels and wheel housings as well.

I would be grateful for any help. Furthermore, if anybody has casestudies on car flow analysis using cosmos, please share or advice.I am in distress.SolidworksFlow Simulation
