Fluid simulation configuration

Fields

rest_density: Fix128

Rest density (kg/m^3)

kernel_radius: Fix128

Smoothing kernel radius

iterations: usize

Number of solver iterations

substeps: usize

Number of substeps

gravity: Vec3Fix

Gravity vector

damping: Fix128

Velocity retention per frame (step() call), applied once per frame since 1.2.0 (per substep before, which made the result depend on substeps)

viscosity: Fix128

Viscosity coefficient (XSPH)

vorticity_strength: Fix128

Vorticity confinement strength ε (Δv = ε · dt · N × ω, PBF §5)

surface_tension: Fix128

Surface tension / cohesion coefficient κ (Δv_i = κ · dt · Σ_j (m_j/ρ₀) (x_j − x_i)/r · W_ij)

particle_mass: Fix128

Particle mass

relaxation: Fix128

Constraint relaxation parameter
