smoke get sucked into jet engine. how do I do that?

I built an engine. Now I want a smoke getting sucked into it. How do I do it?

(I’m new to smoke)

Will be thankful if someone can post good tutorials on smoke simulation.

I created smoke and set all the engine parts as obstacles, but the smoke just flys/hovers and doesn’t get sucked into it. Do I have to set a velocity towards the engine for the smoke?? If so, how?

You could add an empty and give it a force field to attract any smoke that is near it

that made sense, thanks.

shift a in object mode - select force field. All sorts of options. Maybe those will help.
