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)
