I was wondering if these suggestions might be of any interest to you guys, especially for fire simulations.
I noticed in our present project, when we were doing a slow motion explosion simulation, a couple of things which might throw some light on Phoenix's features.
1.We found it a bit hard to control the burning of fire.. lets say, we wanted to keep the burning of the fire for a longer time. A control like
burn rate, where we could say.. Fire can burn longer or burn for shorter time, would have been really helpful.
2. The conservation methods are great, but they inherently change the over all turbulence in the fire, which is fine. But once the conservation is changed, there is hardly any control for the over turbulence. I am not sure if i made sense on this, but I found Multi pass conservation great for fire, but then i couldnt control the size of turbulence inside it. even after changing the methods from buffered to smooth to PCG symmetric. Is it possible to give user a bit of control interms of adding turbulence. I know there is PHX_turbulence node, but as such before adding that, there is inbuilt turbulence inside the fire, any parameter to tweak this would be pretty helpful.
3. Regarding smoke, the dissipation of smoke is great, then again, a parameter to specify when the smoke could dissipate, like giving a threshold value and smoke could start to dissipate, if the smoke goes less or more than that value could be very helpful.
4. Maya fluids have diffusion, where the density of the grid flows into adjacent voxels. A parameter like this, to soften out the smoke would be helpful.
All in all, Phoenix is a phenomenal simulator, especially considering it can do both liquids and fire simulations with such an ease.
If you guys have any work around for the issues i mentioned above, I would love to hear.
Regards
