Expand description

A grid of SPH particles with associated physical quantities.

Positions are stored as flat arrays of (x, y, z) triplets.

Fields§

§positions: Vec<f64>

Particle positions: [x0, y0, z0, x1, y1, z1, …].

§masses: Vec<f64>

Particle masses (one per particle).

§smoothing_lengths: Vec<f64>

Smoothing lengths (one per particle).

§densities: Vec<f64>

Particle densities (one per particle, updated by gpu_density_kernel).

§pressures: Vec<f64>

Particle pressures (one per particle, updated by gpu_pressure_tait).

§velocities: Vec<f64>

Particle velocities: [vx0, vy0, vz0, …].

§forces: Vec<f64>

Particle forces: [fx0, fy0, fz0, …] (output of gpu_force_kernel).

§rho0: f64

Reference density ρ₀ for the Tait equation of state.

§c0: f64

Speed of sound c₀ for the Tait EOS.

Implementations§

Source §

impl GpuSphGrid

Source

pub fn new(n: usize) -> Self

Create a new GpuSphGrid with n particles.

All physical quantities are initialised to zero; rho0 defaults to 1000.0 kg/m³ (water) and c0 to 1500.0 m/s.

Source

pub fn particle_count(&self) -> usize

Number of particles stored in this grid.
