Struct WaterSimGpu 

pub struct WaterSimGpu {
    pub height: FluidGpuBuffer,
    pub velocity: FluidGpuBuffer,
    pub rest_depth: f64,
    pub gravity: f64,
    pub dx: f64,
    pub damping: f64,
}

GPU shallow-water equation (SWE) solver for height field and ripple simulation on a 2-D grid.

Uses the linearised SWE: ∂h/∂t + H ∇·u = 0, ∂u/∂t + g ∇h = 0.

Fields

height: FluidGpuBuffer

Height field h(x, y) — 1 component per cell (m above rest level).

velocity: FluidGpuBuffer

Horizontal velocity field — 2 components (u_x, u_y) per cell.

rest_depth: f64

Rest water depth H (m).

gravity: f64

Gravitational acceleration (m/s²).

dx: f64

Grid cell size (m).

damping: f64

Damping coefficient per step (fraction).
