class Restriction¶

This class represents a restriction of a mesh to a subdomain, which can be defined as a subset of all the cells, the facets, or possibly lower dimensional entities of the mesh.

Restriction(const Mesh &mesh, const SubDomain &sub_domain)¶

Create cell-based restriction from subdomain

Arguments

mesh (Mesh): The mesh
sub_domain (SubDomain): Sub domain defining the restriction

Restriction(const Mesh &mesh, const SubDomain &sub_domain, std::size_t dim)¶

Create restriction from subdomain to entities of arbitrary dimension

Arguments

mesh (Mesh): The mesh
sub_domain (SubDomain): Sub domain defining the restriction
dim (std::size_t): Dimension of restriction

Restriction(const MeshFunction<std::size_t> &domain_markers, std::size_t domain_number)¶

Create restriction from domain markers

Arguments

domain_markers (MeshFunction <std::size_t>): Domain markers for the cells of the mesh.
domain_number (std::size_t): Identifier for domain.

Restriction(std::shared_ptr<const MeshFunction<std::size_t>> domain_markers, std::size_t domain_number)¶

Create restriction from domain markers (shared pointer version)

Arguments

domain_markers (MeshFunction <std::size_t>): Domain markers for the cells of the mesh.
domain_number (std::size_t): Identifier for domain.

const Mesh &mesh() const¶: Return the full unrestricted mesh

std::size_t dim() const¶: Return topological dimension of restriction

bool contains(const MeshEntity &entity) const¶: Check whether restriction contains entity

bool contains(std::size_t d, std::size_t i) const¶: Check whether restriction contains entity (d, i)
