Adding more "curlyness"/vortices

[duke2]

I'm trying to simulate fire (I started from the example) but it just goes straight up. How do I add a higher chance that it will "curl/swirl around"?

Hey,

You have several options there, or a combination of these would work too:
- If the fire not only goes straight up, but moves up too fast, then you need to increase the Scene Scale in the Grid rollout.
- Once the scale looks right, you can increase the conservation quality. It would improve the rolling and fluidity of the sim. There's more on that in the docs.
- Increasing the vorticity would help too.
- You could use a Turbulence helper.
- Or you could use the Randomize option in the Dynamics rollout.

Hope this helps
