Join Aaron F. Ross for an in-depth discussion in this video Colliding particles with geometry, part of Learning RealFlow.
- Now we'll want to adjust the collision properties…for the sink and the drain, in order to…make the particles move more naturalistically.…Select the sink, go over to the Node Params,…and open up Liquid-Particles Interaction,…and these are all the properties for the selected objects.…Collsions: Collision distance is the distance…at which a particle is considered…to be touching the object.…I'm gonna set that to a value of a millimeter.…
Type in a value of 0.001.…Distance Tolerance is a randomization factor…that's going to make it so that the particles don't…sort of sit on top of each other in bands.…We'll give that just a little bit of randomization,…a Distance Tolerance of 0.0001,…or a tenth of a millimeter.…Going down a little bit, we've got Friction.…That's a force that's applied to slow down a moving particle…as it slides across a surface.…
I'm gonna increase the friction a bit,…from 0.001 to 0.01.…Bounce of course is the amount of bounce;…how far apart a particle is going to rebound off a surface.…I'll reduce that a bit. The range is from zero to one.…

4/6/2015You'll learn how to create small-scale effects with standard particles, create free-flowing water effects with the Hybrido solver, and simulate open bodies of water such as oceans and ponds with RealWave. Author Aaron F. Ross also shows how to control interactions between objects and fluids with Caronte, the rigid- and soft-body physics engine included with RealFlow.
