Wow HUGE file....I dont think my laptop can take it LOL. Gubar, you have time to look? I think there are way too many droplets. If you havent done something like this before, I would try with maybe 10% of the droplets you have, to get a feel for what you can and cannot do. Even if you have done this before, I would still reduce the droplets by 90% and get a system going....maybe even on a simple plane etc. Just my thoughts of course, when I am not sure thats what I do...

cheers bullet
