particle_radius	Particle collision / render radius.
solver_iterations	Density-constraint iteration count per step.
epsilon	Small denominator regularizer.
xsph_viscosity	XSPH viscosity coefficient.
vorticity_epsilon	Vorticity confinement coefficient.
use_domain_bounds	Enable domain bounds.
domain_lower, domain_upper	Simulation domain bounds.

Methods

Method	Description
particle_mass(particle_spacing)	Compute particle mass from density and spacing.

Example

import novaphy

cfg = novaphy.solvers.PBFConfig()
cfg.kernel_radius = 4.0 * 0.05
cfg.solver_iterations = 4
cfg.xsph_viscosity = 0.01

solver = novaphy.solvers.SolverPBF(model, cfg)
