Help  Per particle phase change
#2

I'm working on welding simulation.
Is it possible to change per particle properties?
For example, viscosity of a particle can be changed by external heat? and getting colder as time flows?
Is it possible to make some particle become a sleep state and activated by external trigger so the computation load can be optimized.

Thanks!

Hi,

Not currently. Fluid properties (viscosity, rest density, etc) are specified per-material instead of per-particle, to save memory.

Also the viscosity required to transition from fluid to solid is extremely high, well outside of the stability range of any realtime simulation method, so this isn't a practical idea anyway (unless coupled with additional constraints such as shape matching, springs, etc...none of them currently available in ObiFluid).
