This is tutorial from Introduction to Maya Fluid Effects
Volume One: Smoke and Flames by Wayne Hollingsworth. The tutorial is great, everything is clear and it is easy to follow. This is my first meeting with the Maya Fluids, but thanks to Wayne it was painless. But this is only beginning, I think I will have a lot of troubles when start doing own projects using fluids.
One thing I can say the Maya Fluids are really heavy :((...
I recommend this DVD to everyone, good start, because it inspires you to go and learn.
