Collisions

Smoke Collision objects are used to deflect smoke and influence airflow.

To define any mesh object as a Smoke Collision object, add smoke physics by clicking Smoke in Properties ‣ Physics. Then select Collision as the Smoke Type.

Smoke Collision settings.

Collision type
Static
Simple collision model which can be calculated quickly, but may be inaccurate for moving objects.
Animated
More complex collision model which takes into account impulse imparted to smoke when the collider is moving. Calculations are slower, but more accurate for moving objects.
Rigid
Identical to Static (unfinished code).

Forces

Force Fields (such as wind or vortex) are supported, like most physics systems. The influence individual force types have can be controlled per domain object.
