The Simulator → Grid parameters are tweaked as follows: The Scene Scale is set to 5.0. The Cell Size is set to 2.0. The Size of the Simulator is set to [ X:150cm, Y:70cm, Z:140cm ] as a starting point. The Adaptive Grid is set to Smoke. The Adaptive Grid allows the container to resize on-demand as the simulation progresses, saving you a lot of time. Instead of calculating a giant grid from the start, the specified channel is tracked (Smoke in this case) and the grid is automatically resized around it. The Threshold is set to 0.002. The grid will expand when the content of a cell near one of the container walls crosses this value. In this case any Smoke value above 0.002 will cause the grid to expand. Since the Smoke is emitting Smoke 1.0, this means that the grid will be quite sensitive to smoke coming near the grid walls. The Extra Margin is set to 70. This is important, because if left at 0, the Adaptive Grid will not expand fast enough and the horse will be running without emitting dust. The Expand and Don't Shrink is enabled. |
