Vortex acting weird?
Hi guys, I have been stuck on this matter for a long long time.
So I have a very basic torus and a vortex at the center of grid, I disabled gravity, buoyancy, temperature, cooling. Everything I can think of. For vortex, I set axial drop to 0, but somehow the gas always rises and shapes like a hat. My goal is to make the smoke stay at the same level as the torus emitter, which should be the case if there's no force to push it up and down.
Later on, I found out that, as long as this vortex has a radial pull, which should be a horizontal force, it will push the gas vertically. The bigger the radial pull, the more it pushes the air up. This doesn't make any sense, but it seems like the pattern right now.
This kind of strange behavior only happens to PHX, I did tests with tyflow and pflow, their particles all stay on the same plane when affected by the same vortex.
My project requires this radial pull feature, but it causes all the problems. How can I fix this?
Please help!!! Deeply appreciated!
