Smoke - faster dying off rate - shorter adaptive grid

Hello

I am testing this scene. there should be just a bit of smoke emitting from the base of the cylinder - like a smoking tire or something.
the sim would be perfectly fine as it is, but at the later frames take very long to simulate, because the adaptive grid got so long.
could you recommend a technique, how to make the smoke trail shorter, make those particels dye off faster, so the grid doesnt get to long.

also I am searching for a Phoenix video tutorial that just came out lately.
It was covering exactly this topic, showing a car tire burnout sim.
there were some nice tricks how to speed up the sim I remember.
Thnx
Martin

Hey,

You can increase the smoke dissipation in the Dynamics rollout. This will make the smoke fade out over time.

As for the tutorial you’re probably talking about one of these:
