Presentation with moving parts and gas-flow

[Lemans]

Hi all,

I need to build a presentation with moving parts and visual gas-flow.
Think about is as an engine I need to explain using a video.
Do you guy's believe that it's possible?
Don't mined the solids (components) they are easy to create.
Must admit that I do not have experience with animation but found a few tutorials
and it all looks logic. The only thing that I did not found was an example of 'colored
smoke' to simulate some sort of gas-flow.
Maybe there are some plug-ins available but I did not find what I was looking for.
It's not a problem if I need to upgrade to a 'pro' version and/or need to pay for a good
add-on. If it solves my problem it's OK. ( I have looked also at Blender and 3Dmax but
these programs demand weeks before I even can think about starting my task)

Thanks
Lemans
