Hey guys! Please bear with me, I'm an EXTREMELY new user!
So, I have a pyro “billowy smoke” sim and I want the smoke to rise much more than the boundary. How can I do this? What settings do I need to adjust? (Right now, it will rise and then hit the boundary)

Open you autodopnet and click on pyro node. Drag the scale y axis arrow (red) upwards to make the boundary bigger (if you handle tool is not activated, make sure you are using this rather than the select tool).
