Momentum on car

sanchezz · July 28, 2010, 14:11

Hi,

I have simulated a car and acquired lift and drag forces in CFX Post. Now I need the distribution of these forces on the front/rear wheels - how do I do that?

I assume that I have to go somehow over the overall momentum on the car and calculate the forces from there. But I have no clue how to get the momentum, so please help

Cheers

Get the torque on the body about a reference point and get the force on the wheels from that.

sounds good just how do I do that?

Use the torqueX()@location function.
