class MeshDomains

The class MeshDomains stores the division of a Mesh into subdomains. For each topological dimension 0 <= d <= D, where D is the topological dimension of the Mesh, a set of integer markers are stored for a subset of the entities of dimension d, indicating for each entity in the subset the number of the subdomain. It should be noted that the subset does not need to contain all entities of any given dimension; entities not contained in the subset are “unmarked”.

MeshDomains()

Create empty mesh domains

std::size_t max_dim() const

Return maximum topological dimension of stored markers

std::size_t num_marked(std::size_t dim) const

Return number of marked entities of given dimension

bool is_empty() const

Check whether domain data is empty

std::map<std::size_t, std::size_t>& markers(std::size_t dim)

Get subdomain markers for given dimension (shared pointer version)

const std::map<std::size_t, std::size_t>& markers(std::size_t dim) const

Get subdomain markers for given dimension (const shared pointer version)

bool set_marker(std::pair<std::size_t, std::size_t> marker, std::size_t dim)

Set marker (entity index, marker value) of a given dimension d. Returns true if a new key is inserted, false otherwise.

std::size_t get_marker(std::size_t entity_index, std::size_t dim) const

Get marker (entity index, marker value) of a given dimension d. Throws an error if marker does not exist.

const MeshDomains& operator=(const MeshDomains& domains)

Assignment operator

void init(std::size_t dim)

Initialize mesh domains for given topological dimension

void clear()

Clear all data
