Struct Domain 

pub struct Domain {
    pub spatial: SpatialDom,
    pub velocity: VelocityDom,
    pub spatial_res: SpatialRes,
    pub velocity_res: VelocityRes,
    pub time_range: TimeRange,
    pub spatial_bc: SpatialBoundType,
    pub velocity_bc: VelocityBoundType,
    /* private fields */
}

Complete 6D computational domain specification, ready for use by solver components.

Combines spatial/velocity extents, resolutions, boundary conditions, and the time range. Construct via DomainBuilder (see Domain::builder). Frequently-needed floating-point quantities (dx, dv, lx, lv) are cached at construction time to avoid repeated Decimal-to-f64 conversion.

Fields

spatial: SpatialDom

Spatial half-extents (Decimal).

velocity: VelocityDom

Velocity half-extents (Decimal).

spatial_res: SpatialRes

Spatial grid resolution (cell counts per axis).

velocity_res: VelocityRes

Velocity grid resolution (cell counts per axis).

time_range: TimeRange

Simulation start and end times.

spatial_bc: SpatialBoundType

Boundary condition applied along spatial axes.

velocity_bc: VelocityBoundType

Boundary condition applied along velocity axes.

Implementations

impl Domain

pub fn lx(&self) -> [f64; 3]

Spatial half-extents as f64: [L_x1, L_x2, L_x3].

pub fn lv(&self) -> [f64; 3]

Velocity half-extents as f64: [L_v1, L_v2, L_v3].

pub fn cell_volume_3d(&self) -> f64

Spatial cell volume dx1 * dx2 * dx3.

pub fn cell_volume_6d(&self) -> f64
