beeper000 Posted February 6, 2014 Share Posted February 6, 2014 (edited) Hi guys, I have spent the past few weeks watching some tutorials getting to learn Houdini. Right now I'm playing around with pyro FX. I am trying to get a fire ball explosion type of result, like this : http://www.youtube.com/watch?v=A8I_XtD1vmk. ;where the heat cools off and produces smoke. But here the flame or heat just constantly rises, I've been tweaking the values for quite a while now but cant seem to get the heat to die down; heat cutoff doesn't seem to change much. Could you guys help me out on this please? Thanks pyro_v01_01.hip Edited February 7, 2014 by beeper000 Quote Link to comment Share on other sites More sharing options...
rafaelfs Posted February 6, 2014 Share Posted February 6, 2014 (edited) Tweak the cooling rate parameter in your solver, which basically specifies how fast the fluid temperature cools down to zero. Also play with temperature diffusion... Higher values of cooling rate and lower values of temperature diffusion approximate your reference. Cheers Edited February 6, 2014 by rafaelfs Quote Link to comment Share on other sites More sharing options...

Cheers Thanks for the reply Rafael, it did help to some degree but I'm still seeing a lot of the heat in the simulation. Quote Link to comment Share on other sites More sharing options...
