Hello everyone,

I am working under a project "Drafting effect on racing cars".Though everything is done I am under some trouble here.

As in here,drafting,I have two car model with a particular distance between each other and I have to analyse the effect of wake of the front car on the car behind it.

I have to keep changing distance betwwen them,like I have to calculat drag coefficient when the car is 0.1m,0.5m,1.0m,1.5m ...and analyse them in one graph.

So Do I have to change the geometry again and agai and then mesh it again and again.There should be som simple solution.

Help.Any link or tutorial will also do

Thanks.Do reply if you can help.
