Pyro Ambient Temperature and Reference Temp

[isah_voodoo]

Hello,

Is there any rhyme or reason to working with the ambient and reference temperature on the pyro solver ? I can see major differences when I plug in large or small values but I'm really just guessing to see what it will do. I wanted to get some sort of logical explanation for these parameters so that I have an idea on what values I should be putting in and why. 

Would appreciate any advice. 

Thanks

and yes i'm aware it controls the temperature and temperature can make the sim rise up quicker. I am just confused on how to use the Ambient and Reference temp in conjunction with each other

Ambient temp = the sourrounding medias temperature

Reference temp = whatever temperature @ 1.0 gets remapped to (flame temperature)

if Ambient temp>reference temp the smoke will not rise but sink (like dry ice fog). More info.

@nukiThank you for the explanation and link. I'm not sure what you mean by "Reference temp = whatever temperature @ 1.0 gets remapped to (flame temperature)". 

Thanks

See, temperature is just a scalar field. So it gets remapped to kelvin with reference temp as a multiplyer. So if temperature = 1.0, then  kelvin = reference temp * 1.0
Ambient temp on the other hand specifies how many kelvins a temperature value of 0 assumes, so I guess its an additive offset.

theres an explanation in the docs as well

@nukiThanks! This makes more sense.
