Hi,
Can someone explain what the temperature attribute does in FLIP sims? Surprisingly, this attribute is not mentioned in the documentation for the FLIP object, where it is set.

Thanks!

you are talking about viscosity
"Viscous fluids are FLIP simulations that use a temperature attribute to drive viscosity."

Not quite. I know you can tie temperature to viscosity, but viscosity can also be set directly. I don't see the benefit in doing it that way, since there's no explanation in the docs as to the function of temperature in a FLIP sim. What it does to the sim, how it changes over time...
