flcc Posted June 3, 2020 Share Posted June 3, 2020 Hi i facing problem with a smoke sim I have to do. I want my smoke stay within an "elliptical" area. I want this smoke a bit "hairy". sort of magical smoke. this is what I get. I'm pretty happy with this but, while the movement speed are ok, over time the smoke tends to slowly expand. I've try some tweaking between mostly between dissipation and disturbance, but in short it's hairy vs stable. Less hairy more stable, more hairy -> expand. I've also try to supress temperature and juste inject some speed withe a curl noise but don't get expected results. What is the best way to get a smoke "confined" to a specific area ? brainFog.hipnc FogBrain_v2b.mp4 Quote Link to comment Share on other sites More sharing options...
anim Posted June 3, 2020 Share Posted June 3, 2020 there is a shelf tool called attract fluid, you can try playing with that to shape your smoke or also you can create a force based on SDF to try to keep it in, but I guess attract fluid does more stuff to equalize pressure and density 1 Quote Link to comment Share on other sites More sharing options...
flcc Posted June 3, 2020 Author Share Posted June 3, 2020 Works perfectly. I even get an effect closer to what I wanted in the first place. Thousand thanks thomas ! Quote Link to comment Share on other sites More sharing options...
