whats the most efficient-elegant workflow to make the dynamic fluid (simulating cigaret smoke) take a torus shape after going up in the air for 2 or 3 seconds?  
\*i dont want to use the particle technique like duncan did, because i will have to simulate a fluid smoke then let it drive particles (hide both) then let the paricles emit fluid wich will mess up the first clean fluid simulation
