Question: simulate airflow over a vehicle

I'd like Maple to simulate airflow over a specified vehicle shape, and get it to display something similar to this.  ...

arghh.  Can't get pictures to paste, sorry.  So far I've never been able to insert a picture, haven't had the need and so haven't worried about it and now when I want to insert a picture, it's not just a straight forward thing.  Any help with that would be apprecited. 

So is maple able to easily accomplish this or do I need other software like Solidworks Cosmos or Matlab to do the calculations.  My physics is a bit rusty after being out of university for a decade or so.  Some help would be appreciated.
