# TP Nozzle

Back to reference Back to index
The Nozzle preset will compress or expand a stream of particles according to the size of the in and out openings of the nozzle. The preset can be used together with TP Tube for simulation of expanding and compressing nozzles within a tubesystem. During compression or expansion an acceleration can be applied.
On: Activates the Preset. This parameter can be easily animated to switch the emitter on and off as needed
Particle Group: Thinking Particles group that will be used
Input Radius: Radius of the input opening of the nozzle
Output Radius: Radius of the output opening of the nozzle
Length: Length of the Nozzle
Acceleration: Acceleration of particles inside of the nozzle, usualy positive when the nozzle output opening is smaller then the input opening
Strength: Applied force to direct the particles to the output opening depending on the radius
