Join Aaron F. Ross for an in-depth discussion in this video Making collisions, part of Maya: Creating Fluid Effects (2013).
For more realistic simulation we'll want the ponds to collide with the tub, …so that the ripples will actually bounce off the sides of the tub.…If I just play the simulation now it's a pretty close approximation to that…because the pond is actually not that much larger than the tub itself, but we…can make that lot better.…In order to make it more clear what's happening I'm going to increase the emission turbulence. …I want to select the emitter that's in the outliner under…the ducky_control hierarchy, select the emitter and go to its Attributes, Ctrl+A, …and in the Fluid Emission Turbulence, I'm going to set the Turbulence amount to 5 …and increase the speed to 1. That way we will be able to see this much more clearly.…
Playback the simulation, and here with no collisions you'll see that there is a…kind of delay between when the ripple hits the tub wall and when it bounces off,…because it's actually not colliding with the tub just now.…But to make it collide is quite simple.…All we need to do is select the pond and then select the object that we want to collide with.…
