Time Scale is set to 0.1 for attached scenes. Smoke shrinks in the middle of animation.

What is the cause of the problem?

Are you using adaptive grid? Probably you need to tweak the adaptation settings a bit.

[Svetlin.Nikolov]

Adaptive grid is off, but it seems to me that the noise modifier breaks the geometry and creates intersecting faces and inverted normals, which is something Phoenix cannot work with. Maybe a discharge texture mask can achieve a similar effect, otherwise the geometry must be fixed. You could also try switching the conservation from PCG to direct symmetric - PCG is more sensitive to bad geometry.

Hope this helps!

thank you for the advice.
I will try!
