Network Flow

To...	Do this
Create a particle system	You can either use the tab menu in a geometry object, or by use the tools on the Particles shelf. See Emitting for more information.
View the simulation	Make sure the display flag is turn on the POP Solver or a node after it in the network.
Disable POP nodes you don’t want to affect your simulation	You can’t just move the display flag like in old POPs. You must either remove it from the chain, or turn on the bypass flag. The display flag must always be on the POP Solver or a node after it in the network.
Allow other DOPs to affect POPs	Verify the External Forces parameter on the POP Solver is turned on. It should be on by default.
Merge two or more streams	Use a Merge node before the POP Solver.
Switch a node on or off as part of the simulation	Turn on the yellow Bypass flag for the node you want to exclude from the simulation.
