Most attributes of Hybrido core fluid particles are controlled by the solver and cannot be changed, but it is possible to trigger certain events, e.g. to increase the Hybrido emitter's "Speed" parameter dynamically:
| Code Block |
|---|
|
# Initialize the required values
# Get the domain "HY_Domain01" and its particles, get the emitter "HY_Emitter01"
# Read out the emitter's "Speed" parameter and the current number of particles
hybridoDomain = scene.get_HY_GridDomain("HY_Domain01")
hybridoEmitter = scene.get_HY_Emitter("HY_Emitter01")
hybridoParticles = hybridoDomain.getParticles()
emitterSpeed = hybridoEmitter.getParameter("@ Speed")
numOfParticles = len(hybridoParticles)
currentVelocity = 0.0
maxSpeed = 5.0
# Sum up all velocities
for particle in hybridoParticles:
currentVelocity += particle.getVelocity().module()
# Calculate average velocity and avoid illegal division by zero:
if (numOfParticles > 0):
averageVelocity = currentVelocity / float(numOfParticles)
# Check, if average velocity is greater than current emitter speed and smallerless than the given speed limit "maxSpeed"
if (averageVelocity > emitterSpeed and averageVelocity <= maxSpeed):
hybridoEmitter.setParameter("@ Speed", averageVelocity) |
