Struct SphSimulation 

pub struct SphSimulation {
    pub config: SphConfig,
    pub state: SphParticleState,
    pub time: f64,
    /* private fields */
}

SPH simulation that dispatches compute to GPU when available.

Fields

config: SphConfig

Configuration (immutable after construction).

state: SphParticleState

Particle state.

time: f64

Total elapsed simulation time.

Implementations

impl SphSimulation

pub fn new(config: SphConfig) -> Self

Create a new SPH simulation.

pub fn has_gpu(&self) -> bool

True if GPU backend is active.

pub fn step(&mut self, dt: f64)

Advance the simulation by dt seconds.

Steps:

1. Density summation (GPU or CPU)
2. Pressure update (Tait EOS)
3. Pressure + viscosity acceleration
4. Velocity + position integration (symplectic Euler)
5. Boundary reflection

pub fn kinetic_energy(&self) -> f64

Compute total kinetic energy (J) across all particles.

pub fn mean_density(&self) -> f64

Mean density across all particles.
