I wonder what would be the best way to eliminate dead particles from tyFlow. For a reason or another, sometimes small amount of particles stop moving during the simulation. This obviously don't look nice at all. Which operator or setting would be the best way to get rid of those?
You can test their velocity with property test operator (velocity magnitude), and just type in "less then" value.
Finally, connect that property test operator with new event, containing only delete operator.

Yes... less value will probably fix it.
This is in connection with your system units and speed of the particles traveling how many units in 1 frame, from what I understand.
Sometimes, I don't even place delete operator, just a display with high saturated red color, so I clearly see them, until I setup velocity properly, then I add delete operator.
And sometimes, if I see "pop-out" when particles are big, and deleting is obvious (and I don't want it to be obvious), I first test their velocity, bring them into the new event, then animate their scale, to be smaller, and then delete them after 10-15 frames.
This is making them disappear in more natural manner.
You can use a Display Data operator to show just the Velocity values of the bastard particles that need to die. Type a similar value into the Property test and you should be good.
I reactivated the property test and changes the value to 0.001 mm. On the preview display I can't see any still particles. So I copied the cache to rendering queue to see if there are any dead particles on rendered animation.
