Difference between using geomery and volumes for flip sims

Recommended Posts

Posted (edited)

Hi. 

I am crawling from being a Houdini beginner to intermediate and with flip sims I had a few ques:

1. Both geometry and volumes can be used to construct flip simulations. I'm not quite sure when one might chose one over the other and specifically when you might feed a volume into the flip solver. (is the post solve input, the input for the volume?)

2. When building a flip sim i'm a bit confused when you would use the flip source node. You can just use the geometry as the sop path for a flip object in the dop network. So why/when would you use the flip source node?

Thanks

#2.) Supplying geometry to the SOP path gives you a one-time injection of particles in that shape. (on the creation frame). With the volume source node, you can "source" inject particles every frame. So, you could emulate the SOP path using the volume source and only activate it on frame #1. The volume source is for continuous activation.
