Hello! I'm new to Houdini, please help!!! I need a small tornado from the fountain that enveloping the character's arm. I try to do this in a simulation, but I can not get a stable beautiful shape. I've tried to do custom velocity field like that too (https://www.youtube.com/watch?v=z19fxCbe2Eg), but still don't get stabil tornado shape. 
Also,I noticed that if I make a simulation in real size, then it is even more unstable and not beautiful(maybe I'm doing something wrong). 
The tornado should react to changing the position of the hand (hand is mooving back and forth). And do not know how to achieve the shape of whilrpool,as at my picture(https://drive.google.com/file/d/1RzsZPUETZj7HBtS9D6reTGn-YSPKnUZc/view?usp=sharing). Please, help!
