Fire simulation just dies out on its own

Here is the problem : very basic simulation, an emitter, a domain, some wind. As you can see in the video, it starts out as you’d expect, and then just “explodes” into nothing. I tried changing the emitter, the domain, but it keeps doing that… Any idea ?

Thanks a lot !

If you emitter is not particle based, try sourcing from particles, not a surface, then you can use particle forces, instead of wind, to control the shape.

Also, turn off dissolve on the Domain and see if your dissipation problem goes away.
Remove the wind and test if that is the problem.
