Affect [ Liquid ] | affectpartsys – Allows the Particle Tuner to separately affect the Liquid, Foam, Splash or Mist particles.  You can also affect Drag particles in a Fire/Smoke simulation, but note that you cannot change their Velocity channel - they are simply dragged by the fluid. You could affect any Drag particle system by typing Drag in the list, or you can affect specific Drag particle systems by using their exact names.

When [ Edit Condition... ] – Opens the Edit Condition window. The Edit Condition window is used to construct a sequence of tests which are evaluated for every particle of the Phoenix FD Simulator. If the particle satisfies the condition, the Then [ Particle Channel ] action is performed. Otherwise, the particle is ignored. By default, the condition is set to "Age > 1.000", therefore only those particles whose age is greater than one will be affected by the specified Action.
