Particle Properties

Every particle has a wide variety of properties such as velocity, id, density, or vorticity:

• These attributes can be read out and user for further calculations or actions.
• RealFlow's different particle types also have different numbers of attributes.

To get the properties, a loop is necessary – here for a Dyverso domain, but the concept is exactly the same for Hybrido domains and standard particle emitters:

# Mind the leading spaces, because otherwise you will get syntax errors!
dyversoDomain    = scene.get_DY_Domain("DY_Domain01")
dyversoParticles = dyversoDomain.getParticles()
 
for singleParticle in dyversoParticles:
	particleAge      = singleParticle.getAge()
	particleVelocity = singleParticle.getVelocity()
	particleId       = singleParticle.getId()
	particlePosition = singleParticle.getPosition()

In the script above, the properties are read out with a get... command. With the appropriate set... commands it is possible to define new position and velocity vectors.
