Hi
So I want to make the smoke fill the spiral tube and I'm pretty close to result I've been aiming for but i've run into a problem I can't seem to resolve. At one point in the simulation smoke stops responding to forces and just follows the tube (attachment).
My process of making this set up:
1. convert tube to volume
2. attract billowy smoke emitted from sphere to the volume tube (attract fluid)
3. add a curve force (curve was used to make the tube so it is in the middle of the tube)
I've tried changing every paramiter I could think of but nothing helped. Anyone has any ideas?
