– Time Scale controls the speed of the simulation.
– Low values result in a “slow motion” simulation, while higher values result in a “faster motion”.
– Attention: changing the Time Scale parameter is not the same as speeding up or slowing down a video. Time Scale affects the whole simulation giving you different shapes of the fire/smoke.
– Something that can help to understand: imagine the video on the left as a very big explosion watched from very far and the video on the right as a small one watched from near!
