Dyverso Domains

Add script to Simulation Flow (Ctrl/Cmd + F2) > FramesPre or StepsPre.

Find a particle's neighbours in domain "DY_Domain01" and the given search radius. The number of neighbours will be displayed for every particle:

# Get the domain "DY_Domain01" and its particles
dyversoDomain   = scene.get_DY_Domain("DY_Domain01")
domainParticles = dyversoDomain.getParticles()
searchRadius    = 0.2

# Loop through every particle, read out its position
for particle in domainParticles:
	particlePos = particle.getPosition()
 
	# Search for neighbours at the particle's position and within the given radius
	neighbours = dyversoDomain.getNeighbors(particlePos, searchRadius)

	# Print out how many particles were found
	scene.message(str(len(neighbours))+" neighbour particles found for particle "+str(particle.getId()))

Standard Particle Fluid Emitters

Add script to Simulation Flow (Ctrl/Cmd + F2) > FramesPre or StepsPre.

Find a particle's neighbours in emitter "Square01" and the given search radius. The number of neighbours will be displayed for every particle:

# Get the standard particle emitter "Square01" and its particles
emitter          = scene.get_PB_Emitter("Square01")
emitterParticles = emitter.getParticles()
searchRadius     = 0.2

# Loop through every particle 
for particle in emitterParticles:
 
	# Search for neighbours within the given radius	
	neighbours = particle.getNeighbors(searchRadius)

	# Print out how many particles were found
	scene.message(str(len(neighbours))+" neighbour particles found for particle "+str(particle.getId()))

Hybrido Domains

A comparable function is not available for Hybrido core fluid particles or secondary fluid particles.
