The Simulator → Grid parameters are tweaked as follows: The Scene Scale is set to 25.0. When working with small scale water simulations, it's often hard to control the tiny jittering that tends to occur near collision objects without increasing the Steps Per Frame to prohibitively high values. Therefore, it's faster and easier to simply increase the Scene Scale a little. If your scene setup requires lower Scene Scale, you can compensate this by increasing the Steps Per Frame at the expense of increased simulation time. The Cell Size is set to 0.15 cm. The lower the Cell Size is, the more detailed the simulation will be but the longer it will take to complete. We start off with a reasonably small value so we can iterate quickly over different parameter variations. The X/Y/Z Size of the Simulator is set to 190/190/170. Increasing the Grid Resolution of the Grid can sometimes alter the shape and behavior of the simulation. Remember that higher resolution does not necessarily mean more realistic simulations. It depends on the project. Sometimes the resolution is too high, and there are too many details, or the look is not what you want. You have to find a good balance. |
