I have one point as a pyro source emitter and there's no other forces exerted upon it besides buoyancy, so what I would expect to see is a symmetrical mushroom like shape coming about.

Explain, please?

I also did an OpenCL version, resulting in a similar asymmetrical shape of smoke.

So where does this mysterious 'disturbance force' come from?

From everyone the past 15 years wanting NO mushrooms in sims?

This is what I can get from DOP pyro solver by bringing in the one point emitter. The smoke is not strictly symmetrical but looks more correct than SOP pyro solver.

But still I don't understand what's hiding behind the scenes!

@johnmather

Sirs, could you help with this?

I believe I could get better control of pyro shape if I understand this.

Can't you just use dissipate to clip the flame much lower on the smooth part?

There's probably some rather sophisticated equations working inside Pyro Solvers that causes disturbance of smoke. The more pertinent question is how to minimise such disturbance (which sometimes can be too strong obviously as if some sort of turbulent force were being put in there) and tweak it to my liking?
