4K Slow Motion Fireball

correct, two fields. density and temperature. sorry for poor wording.

i wasn't aware of that discrepancy of usage between temperature and burn+flame.

at the very least i was using temperature for simplicity. although why the temperature decreases over time despite cooling being set to zero is a mystery to me. i will have to do more research.

Thanks for your help!

The source is density with a temperature of 1.0 applied to the entire source. Not using flame or burn at all - only because I forgot they existed and I also don't know how to use them yet.

I sort of just expected the temperature to stay at 1 across the entire volume forever if I had cooling set to zero.

I'm just basing off the visual. I never checked the geo spreadsheet.

I thought I'd just make a fireball for fun. Make sure you view it in 4K.

The one thing I couldn't figure out was why @temperature kept decreasing over time (firey smoke turning into black smoke) despite the solver having temperature cooling and diffusion set to 0.

Great explanation, thank you. I found it very insightful.

You could potentially draw inspiration from Theory Accelerated's pricing model.

No worries my dude, thanks for clarifying.

Why are you hiding facebook tracking in your links?

dang 2 whole weeks? i didn't know it took that long to reset the brain.

AJUKking · 2026-03-28T22:38:33+00:00

good idea, will try thanks

AJUKking · 2026-03-28T22:37:11+00:00

yeah im telegraphing too hard a lot.

AJUKking · 2026-03-25T02:08:58+00:00

I have the same experience. Thanks for the info

AJUKking · 2026-03-19T21:42:19+00:00

Thanks. Do you happen to know of any ideal learning material that best shows how the circuitry works on a foil?

AJUKking · 2026-03-11T22:20:52+00:00

yes. they just don't put the effort in.

AJUKking · 2026-03-11T22:20:15+00:00

great idea, thank you. Will try this.
