Simulating two cars with FloWorks 2008
 
Hello guys, I'm new to this forum. I am trying to simulate two cars (one behind the other) to figure out the drag force applied to the cars. I have set 2 surface goals on each of the cars. Currently I am running them on a 2D plane flow and I set the width of the domain to width of the car. It's giving me incorrect numbers. I am wondering whether i should run it on a 3D flow (which takes 10 billion years) ? Or am i missing something else here. please help...... :(
