Go to the Dynamics rollout. Make sure to disable the Gravity option, since we don't want the liquid to actually fall down. Take a look at the other parameters in this rollout. For ease, here are the set values: Steps Per Frame is set to 2. In the comparison example you can see how dramatic SPF is affecting the liquid mesh. The default value of 1 makes the liquid too diffused. Check a comparison image for the Steps Per Frame parameter. Time Scale is set to 0.9. Note that, the lower the Time Scale, the slower the movement of the liquid will be. It also affects the so called "sticky look". Check the comparison Time scale example below. Default Viscosity is set to 0.01. Check the comparison example of Viscosity below. Surface Tension Strength controls the force produced by the curvature of the liquid surface. This parameter plays an important role in small-scale liquid simulations because an accurate simulation of surface tension indicates the small scale to the audience. Lower Surface Tension values will cause the liquid to easily break apart into individual liquid particles, while higher values will make it harder for the liquid surface to split and will hold the liquid particles together. With high Surface Tension, when an external force affects the liquid, it would either stretch out into tendrils, or split into large droplets. Droplet Breakup controls the balance between tendrils or droplets formed by the liquid. Droplet Radius controls the radius of the droplets formed by the Droplet Breakup parameter. Check the result of experimenting with those Surface Tension parameters below. In this tutorial we use the balanced values of 1.0 for Droplet Breakup and Strength, and 2.5 for Droplet Radius. |
