Flow simulation crashes on generate flow trajectories

Hello,

I have succesfully created a flow simulation of my model for the F1 in Schools challenge (Model made in Inventor and imported as a STEP file):

http://dl.dropbox.com/u/41931267/Flow%20Simulation%20FrontUpBackDown.SLDPRT

I can export the global goals and create a surface plot, but as when I try to generate Flow Trajectories, the progress bar remains at 0% and any clicking will result in a crash.

Thank you for your help.
