class sofia.domain.particle_domain.ParticleDomain(ndim: Literal[1, 2, 3] = 3, name: str = 'P', _n_particles: Expr | int | None = None, _extent: Tuple | None = None, _smoothing_length: Expr | float | None = None)

Bases: Domain

Symbolic representation of a particle domain.

A domain where fields are indexed by particle. Particles live in ndim-dimensional Cartesian space.

Parameters:

• ndim – Spatial dimensionality.

• name – Name used to identify the particle domain.

property smoothing_length: Expr

Cutoff radius of every NeighbourSum on this domain.

concrete(n_particles: int | None = None, extent: tuple[Numeric | tuple[Numeric, Numeric] | list[Numeric], ...] | list[Numeric | tuple[Numeric, Numeric] | list[Numeric]] | Numeric | None = None, smoothing_length: float | None = None, subs: dict | None = None) → dict[Symbol, int | float]

Return substitutions corresponding to the concrete numbers of the domain.
