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. Please, help!

I have. But the suction force pushes the particles forward a little, increases speed and changes the shape. But I need to create a shape that is in the picture. Also the whirlpool should appear and rotate slowly :(

what about a more procedural approach like this, I am not saying that it couldn't be done using particles, but this seems like the kind of things I would approach splitting the effect in different parts, one would be the waterfall, and the other one would be the wrilpool, and then at the end I would mix everything with secondary particles, spray and stuff like that.
