  • I've got one more question, as you can see in this video, I've got two additional problems. One being that for some reason it shakes like crazy, I think the domain may be moving...?

The other one is, why does the smoke get cut off at the beginning of the video and is only a full "flow" when it reaches the other side? vid.me/aNI5 Thanks for your help. – gogonimago Jan 30 '15 at 3:44
  • @gogonimago For a separate problem it's best to ask a new question. That said, is it possible you could upload your .blend? – gandalf3 Jan 30 '15 at 7:02
