Struct VorticityConfinement

Source

pub struct VorticityConfinement {
    pub strength: f64,
}

Expand description

Vorticity confinement adds back dissipated rotation energy.

A positive strength amplifies existing vorticity, keeping swirling structures alive longer.

Fields§

§strength: f64

Confinement coefficient (dimensionless, typically 0.01 – 0.5).

Implementations§

Source §

impl VorticityConfinement

Source

pub fn new(strength: f64) -> Self

Create a new vorticity confinement operator.

Source

pub fn compute_vorticity(&self, grid: &MacGrid) -> Vec<f64>

Compute the scalar vorticity (∂u_y/∂x − ∂u_x/∂y) at every cell centre.

Returns a flat Vecf64of lengthnx * ny`.

Source

pub fn apply_confinement_force(&self, grid: &mut MacGrid, dt: f64)

Apply the vorticity confinement force to grid.

Computes f = strength * dx * η × (∇|ω| / |∇|ω||) and adds it to the face velocities.
