Calculating drag using solidworks flow simulation

Hi,

I'd like to compare the drag produced on different models.

I'd like to put simulate air being shot at them at 90mph and then compare the results.

How can I go about this? I can set up a test but I'm unsure how to interrupt the results/find the drag etc.

Thanks, if anyone can help me I'd be willing to pay for a small online lesson on how it works.
